This switches the unit to Restart=on-failure and switches the CPU policy
to fifo (the daemon tries to do that itself, but is denied permission).
Also add the package to $PATH to be able to use fs_cli easily.
It's pbPort, and it's also a connection string, meaning
listen-on-localhost is also possible. Provide an alias for the old
option name, so old configs still work.
This patch was done by curro:
The generated /etc/pam.d/* service files invoke the pam_systemd.so
session module before pam_mount.so, if both are enabled (e.g. via
security.pam.services.foo.startSession and
security.pam.services.foo.pamMount respectively).
This doesn't work in the most common scenario where the user's home
directory is stored in a pam-mounted encrypted volume (because systemd
will fail to access the user's systemd configuration).
This fixes a regression from 993baa587c which requires
networking.hostName to be a valid DNS label [0].
Unfortunately we missed the fact that the hostnames may also be empty,
if the user wants to obtain it from a DHCP server. This is even required
by a few modules/images (e.g. Amazon EC2, Azure, and Google Compute).

Fixes this warning at ibus-daemon startup:
(ibus-dconf:15691): dconf-WARNING **: 21:49:24.018: unable to open file '/etc/dconf/db/ibus': Failed to open file ?/etc/dconf/db/ibus?: open() failed: No such file or directory; expect degraded performance
xchg is advertised as a bidirectional exchange dir, but file content
transfer from host to VM fails due to caching:
If a file is read in the VM and then modified on the host, subsequent
re-reads in the VM can yield old, cached data.
This is caused by the use of 9p's cache=loose mode that is explicitly
meant for read-only mounts.
9p doesn't provide any suitable cache modes, so fix this by disabling
caching.
Also, remove a now unnecessary sync in the test driver.
This effectively disables nscd's built-in hosts cache, which turns out
to be erratic in some cases.
We only use nscd these days as a more ABI-neutral NSS dispatcher
mechanism.
Local caching should still be possible with local resolvers in
/etc/resolv.conf (via the `dns` NSS module), or without local resolvers
via systemd-networkd (via the `resolve` nss module)
We don't set enable-cache to no due to
https://github.com/NixOS/nixpkgs/pull/50316#discussion_r241035226.
Refactor the systemd service definition for the haproxy reverse proxy,
using the upstream systemd service definition. This allows the service
to be reloaded on changes, preserving existing server state, and adds
some hardening options.
Because this script enables `set -u` when no arguments are provided bash
exits with the error:
$1: unbound variable
instead of the helpful usage message.
These syncs have the goal to transfer host filesystem changes to the VM,
but they have no effect because 1) syncing in the VM can't possibly pull
in host data and 2) 9p is accessing the host filesystem on the cached
layer anyways, so even syncing on the host would have no effect in the
VM.
The `networking.interfaces.<name?>.proxyARP` option previously mentioned it would also enable IPv6 forwarding and `proxy_ndp`.
However, the `proxy_ndp` option was never actually set (the non-existing `net.ipv6.conf.proxy_arp` sysctl was set
instead). In addition `proxy_ndp` also needs individual entries for each ip to proxy for.
Proxy ARP and Proxy NDP are two different concepts, and enabling the latter
should be a conscious decision.
This commit removes the broken NDP support, and disables explicitly
enabling IPv6 forwarding (which is the default in most cases anyways)
Fixes#62339.
NixOS currently has issues with setting the FQDN of a system in a way
where standard tools work. In order to help with experimentation and
avoid regressions, add a test that checks that the hostname is
reported as the user wanted it to be.
Co-authored-by: Michael Weiss <dev.primeos@gmail.com>
This fixes the output of "hostname --fqdn" (previously the domain name
was not appended). Additionally it's now possible to use the FQDN.
This works by unconditionally adding two entries to /etc/hosts:
127.0.0.1 localhost
::1 localhost
These are the first two entries and therefore gethostbyaddr() will
always resolve "127.0.0.1" and "::1" back to "localhost" [0].
This works because nscd (or rather the nss-files module) returns the
first matching row from /etc/hosts (and ignores the rest).
The FQDN and hostname entries are appended later to /etc/hosts, e.g.:
127.0.0.2 nixos-unstable.test.tld nixos-unstable
::1 nixos-unstable.test.tld nixos-unstable
Note: We use 127.0.0.2 here to follow nss-myhostname (systemd) as close
as possible. This has the advantage that 127.0.0.2 can be resolved back
to the FQDN but also the drawback that applications that only listen to
127.0.0.1 (and not additionally ::1) cannot be reached via the FQDN.
If you would like this to work you can use the following configuration:
```nix
networking.hosts."127.0.0.1" = [
"${config.networking.hostName}.${config.networking.domain}"
config.networking.hostName
];
```
Therefore gethostbyname() resolves "nixos-unstable" to the FQDN
(canonical name): "nixos-unstable.test.tld".
Advantages over the previous behaviour:
- The FQDN will now also be resolved correctly (the entry was missing).
- E.g. the command "hostname --fqdn" will now work as expected.
Drawbacks:
- Overrides entries form the DNS (an issue if e.g. $FQDN should resolve
to the public IP address instead of 127.0.0.1)
- Note: This was already partly an issue as there's an entry for
$HOSTNAME (without the domain part) that resolves to
127.0.1.1 (!= 127.0.0.1).
- Unknown (could potentially cause other unexpected issues, but special
care was taken).
[0]: Some applications do apparently depend on this behaviour (see
c578924) and this is typically the expected behaviour.

https://github.com/NixOS/nixpkgs/pull/88492 flipped some references to
systemctl from config.systemd.package to /run/current-system/systemd/,
which udevRules obviously isn't able resolve.
If we encounter such references, replace them with
config.systemd.package before doing the check.
The `network-link-${i.name}` units raced with other things trying to
configure the interface, or ran before the interface was available.
Instead of running our own set of shell scripts on boot, and hoping
they're executed at the right time, we can make use of udev to configure
the interface *while they appear*, by providing `.link` files in
/etc/systemd/network/*.link to set MACAddress and MTUBytes.
This doesn't require networkd to be enabled, and is populated properly
on non-networkd systems since
https://github.com/NixOS/nixpkgs/pull/82941.
This continues clean-up work done in
https://github.com/NixOS/nixpkgs/pull/85170 for the scripted networking
stack.
The only leftover part of the `network-link-${i.name}` unit (bringing
the interface up) is moved to the beginning of the
`network-addresses-${i.name}` unit.

it does happen that `dnscrypt-proxy` exit when it is unable to
synchronise its resolvers metadata on startup. this can happen due
to network connectivity issues for example. not restarting it automatically
means no dns resolution will work until a manual restart is performed.
Favor the configuration in "configFile" over "config" to allow
"configFile" to override "config" without a system rebuild.
Add a "persistentKeys" option to generate keys and addresses that
persist across service restarts. This is useful for self-configuring
boot media.
Accessing the configured port of a service is quite useful, for example
when configuring virtual hosts for a service. The prometheus module did
not expose the configured por separately, making it unnecessarily
cumbersome to consume.
This is a breaking change only if you were setting `listenAddress` to
a non-standard value. If you were, you should now set `listenAddress`
and `port` separately.
This ensures a correct DBUS_SESSION_BUS_ADDRESS environment variable
is set and imported into the systemd user environment.
Previously this would refer to a non-existing path preventing commands
interacting with the systemd manager from working.

This adds a simple test running GNU Hello cross-compiled for armv7l and

`/proc/sys/fs/binfmt_misc` as soon as systemd-binfmt tries to access it.

The 6.0 changelog notes that systemd support was rewritten. The effects
of that seem to be twofold:
* Redis will silently fail to sd_notify if not built with libsystemd,
breaking our unit configuration.
* It also appears to misbehave if told to daemonize when running under
systemd -- note that upstream's sample unit configuration does not
daemonize:
https://github.com/antirez/redis/blob/unstable/utils/systemd-redis_server.service
Currently, sudo doesn't work in a NixOS container running inside a Nix
build, because Nix's seccomp filter doesn't allow setuid programs. In
any case, runuser is a bit lower-overhead than sudo.
I hate the thing too even though I made it, and rather just get rid of
it. But we can't do that yet. In the meantime, this brings us more
inline with autoconf and will make it slightly easier for me to write a
pkg-config wrapper, which we need.
A disabled nscd breaks nss module loading on NixOS, and systemd without
its nss modules doesn't really work either - instead of silently
disabling its nss modules if nscd is disabled, let the assertion in
nsswitch handle this.
nixos/modules/config/nsswitch.nix uses `passwdArray` for both `passwd`

The configured mbuffer path will be called on both the source and target
system. If you use pkgs.mbuffer from the source host and the target host
does not have this exact derivation, you will get a broken pipe when
sending snapshots. This is the case when transferring to a non-NixOS
system or to a host with a different mbuffer version.
In /etc/doas.conf, the last-matched rule will override all
previously-matched rules. Thus, make the default rule show up first (but
still allow some wiggle room for a user to `mkBefore` it), before any
user-defined rules.
the options should not be set as we already change user with service
file, man mpd.conf says "Do not use this option if you start MPD as an
unprivileged user"
The group option actually is not documented at all anymore and probably
no longer exists.
These options get in the way of setting up confinement for the service,
as it would otherwise be pretty straightforward to setup, but even if
mpd is not root it would check the user exists within the chroot which
is more work (need to get nss working):
systemd.services.mpd = {
serviceConfig.BindPaths = [
# mpd state dir
"/var/lib/mpd"
# notify systemd service started up
"/run/systemd/notify"
];
serviceConfig.BindReadOnlyPaths = [
"/path/to/music:/var/lib/mpd/music"
];
# ProtectSystem is not compatible with confinement
serviceConfig.ProtectSystem = lib.mkForce false;
confinement = {
enable = true;
binSh = null;
mode = "chroot-only";
};
};
Systemd ProtectSystem is incompatible with the chroot we make
for confinement. The options is redundant with what we do anyway
so warn if it had been set and advise to disable it.

This test is sometimes flaky on hydra as at the time of the `git clone`
the network isn't really configured yet[1]. That problem doesn't seem to
occur locally but if you run it on a machine with high enough load (such
as hydra build machines). Hopefully this will make the test not flaky
anymore.

The test harness provides the commands it wishes to run in Bourne

By default, postgres prefixes each log line with a timestamp. On NixOS
logs are written to journal anyway, so they include an external
timestamp, so the timestamp ends up being printed twice, which clutters
the log.
* Add a module option to change the log prefix.
* Set it to upstream default sans timestamp.
This completes the removal of the nested log feature, which previously
got removed from Nix, Hydra, stdenv and GNU Make. In particular, this
means that the output of VM builds no longer contains a copy of
jQuery.
If a program (e.g. nixos-install) writes more than 1000 lines to
stderr during execute(), then process_serial_output() deadlocks
waiting for the queue to be processed. So use an unbounded queue
instead.
We should probably get rid of the structured log output (log.xml),
since then we don't need the log queue anymore.
'nix build' is an experimental command so we shouldn't use it
yet. (nixos-rebuild also uses 'nix', but only when using flakes, which
are themselves an experimental feature.)
This reverts commits 9d0de0dc57,
27d2857a99. 'nix ping-store' is an
experimental command so it doesn't work in Nix 2.4 unless you set
'experimental-features = nix-command' in nix.conf.
This seems to have worked in 15f105d41f (5
months ago) but broke somewhere in the meantime.
The current module doesn't seem to be underdocumented and might need a
serious refactor. It requires quite some hacks to get it to work (see
https://github.com/NixOS/nixpkgs/issues/86305#issuecomment-621129942),
or how the ldap.nix test used systemd.services.openldap.preStart and
made quite some assumptions on internals.
Mic92 agreed on being added as a maintainer for the module, as he uses
it a lot and can possibly fix eventual breakages. For the most basic
startup breakages, the remaining openldap.nix test might suffice.
`doas` is a lighter alternative to `sudo` that "provide[s] 95% of the
features of `sudo` with a fraction of the codebase" [1]. I prefer it to
`sudo`, so I figured I would add a NixOS module in order for it to be
easier to use. The module is based off of the existing `sudo` module.

Add extraConfig option for the muc submodule.
Also move the global extraConfig before all components and
virtualhosts, because the manual states:
The configuration is divided into two parts. The first part is known as
the "global" section. All settings here apply to the whole server, and
are the default for all virtual hosts.
The second half of the file is a series of VirtualHost and Component
definitions. Settings under each VirtualHost or Component line apply
only to that host.
Before, if at least one muc was defined, or uploadHttp enabled, the
global extraConfig would end up after "muc" or "http_upload" component
making it apply to that component only and not globally.
We add a Prosody entry to the NixOS manual showing how to setup a

me, it's necessary. If we try to increase their indentation level, the

This reverts commit 764c8203b8.
While this is desireable in principle, some of our modules and services
fail during service startup if no network is available don't currently
properly set Wants=network-online.target.
If nothing pulls in this target anymore, systemd won't try to reach it.
We have many VM tests waiting for `network-online.target`, and after
764c8203b8 fail with the following error
message:
```
error: unit "network-online.target" is inactive and there are no pending jobs
```
Most likely, test scripts shouldn't wait for `network-online.target` in
first place (as `network-online.target` says nothing about whether a
service has been started), but instead, the script should wait for the
network ports of the corresponding service to be open.
Let's revert this for now, and re-apply in a draft PR, fixing the tests
before merging it back in.
This is a follow-up to the PR #82026 that contains the promised tests.
In this test I am testing if we can properly propagate prefixes received
via DHCPv6 PD with the networkd options in our module system.
The comments in the test should be sufficient to follow the idea and
what is going on.
The output file is found and handled by thelounge itself [1], leaving
the user free to override THELOUNGE_HOME in the environment if they
choose, but having a sensible default to make `thelounge` generally
usable in most cases.
This solution follows discussion on #70318.
[1] 9ef5c6c67e/src/command-line/utils.js (L56)
This follows upstreams change in documentation. While the `[DHCP]`
section might still work it is undocumented and we should probably not
be using it anymore. Users can just upgrade to the new option without
much hassle.
I had to create a bit of custom module deprecation code since the usual
approach doesn't support wildcards in the path.
You can now specify option for the `[DHCPv6]` section with
`systemd.network.<name>.dhcpV6Config.…`. Previously you could only use
the combined legacy DHCP configuration.
Systemd upstream has deprecated CriticalConnection with v244 in favor of
KeepConnection as that seems to be more flexible:
The CriticalConnection= setting in .network files is now deprecated,
and replaced by a new KeepConfiguration= setting which allows more
detailed configuration of the IP configuration to keep in place.
We are leveraging the systemd sandboxing features to prevent the
service accessing locations it shouldn't do. Most notably, we are here
preventing the prosody service from accessing /home and providing it
with a private /dev and /tmp.
Please consult man systemd.exec for further informations.
Setting up a XMPP chat server is a pretty deep rabbit whole to jump in
when you're not familiar with this whole universe. Your experience
with this environment will greatly depends on whether or not your
server implements the right set of XEPs.
To tackle this problem, the XMPP community came with the idea of
creating a meta-XEP in charge of listing the desirable XEPs to comply
with. This meta-XMP is issued every year under an new XEP number. The
2020 one being XEP-0423[1].
This prosody nixos module refactoring makes complying with XEP-0423
easier. All the necessary extensions are enabled by default. For some
extensions (MUC and HTTP_UPLOAD), we need some input from the user and
cannot provide a sensible default nixpkgs-wide. For those, we guide
the user using a couple of assertions explaining the remaining manual
steps to perform.
We took advantage of this substential refactoring to refresh the
associated nixos test.
Changelog:
- Update the prosody package to provide the necessary community
modules in order to comply with XEP-0423. This is a tradeoff, as
depending on their configuration, the user might end up not using them
and wasting some disk space. That being said, adding those will
allow the XEP-0423 users, which I expect to be the majority of
users, to leverage a bit more the binary cache.
- Add a muc submodule populated with the prosody muc defaults.
- Add a http_upload submodule in charge of setting up a basic http
server handling the user uploads. This submodule is in is
spinning up an HTTP(s) server in charge of receiving and serving the
user's attachments.
- Advertise both the MUCs and the http_upload endpoints using mod disco.
- Use the slixmpp library in place of the now defunct sleekxmpp for
the prosody NixOS test.
- Update the nixos test to setup and test the MUC and http upload
features.
- Add a couple of assertions triggered if the setup is not xep-0423
compliant.

When testing WireGuard updates, I usually run the VM-tests with
different kernels to make sure we're not introducing accidental
regressions for e.g. older kernels.
I figured that we should automate this process to ensure continuously
that WireGuard works fine on several kernels.
For now I decided to test the latest LTS version (5.4) and
the latest kernel (currently 5.6). We can add more kernels in the
future, however this seems to significantly slow down evaluation and
time.
The list can be customized by running a command like this:
nix-build nixos/tests/wireguard --arg kernelVersionsToTest '["4.19"]'
The `kernelPackages` argument in the tests is null by default to make
sure that it's still possible to invoke the test-files directly. In that
case the default kernel of NixOS (currently 5.4) is used.
The elasticsearch-curator was not deleting indices because the indices

Not all systems need to be online to boot up. So, don’t pull
network-online.target into multi-user.target. Services that need
online network can still require it.
This increases my boot time from ~9s to ~5s.
It's `lib.versions`, not `lib.version`. Also I'm really sure that it's
supposed to be the current version of Gutenprint, not Cups, as thats
what `lpinfo -m` says on my system.
Rework withExtensions / buildEnv to handle currently enabled
extensions better and make them compatible with override. They now
accept a function with the named arguments enabled and all, where
enabled is a list of currently enabled extensions and all is the set
of all extensions. This gives us several nice properties:
- You always get the right version of the list of currently enabled
extensions
- Invocations chain
- It works well with overridden PHP packages - you always get the
correct versions of extensions
As a contrived example of what's possible, you can add ImageMagick,
then override the version and disable fpm, then disable cgi, and
lastly remove the zip extension like this:

let
phpWithImagick = php74.withExtensions ({ all, enabled }: enabled ++ [ all.imagick ]);

Instead of hardcoding all nss modules that are added into nsswitch,
there are now options exposed.
This allows users to add own nss modules (I had this issue with
winbindd, for example).
Also, nss modules could be moved to their NixOS modules which would
make the nsswitch module slimmer.
As the lists are now handled by the modules system, we can use mkOrder
to ensure a proper order as well as mkForce to override one specific
database type instead of the entire file.

Shimming out the Let's Encrypt domain name to reuse client configuration
doesn't work properly (Pebble uses different endpoint URL formats), is
recommended against by upstream,[1] and is unnecessary now that the ACME
module supports specifying an ACME server. This commit changes the tests
to use the domain name acme.test instead, and renames the letsencrypt
node to acme to reflect that it has nothing to do with the ACME server
that Let's Encrypt runs. The imports are renamed for clarity:
* nixos/tests/common/{letsencrypt => acme}/{common.nix => client}
* nixos/tests/common/{letsencrypt => acme}/{default.nix => server}
The test's other domain names are also adjusted to use *.test for
consistency (and to avoid misuse of non-reserved domain names such
as standalone.com).

This was added in aade4e577b, but the
implementation of the ACME module has been entirely rewritten since
then, and the test seems to run fine on AArch64.
These now depend on an external patch set; add them to the release tests
to ensure that the build doesn't break silently as new kernel updates
are merged.
linux-hardened sets kernel.unprivileged_userns_clone=0 by default; see
anthraxx/linux-hardened@104f44058f.
This allows the Nix sandbox to function while reducing the attack
surface posed by user namespaces, which allow unprivileged code to
exercise lots of root-only code paths and have lead to privilege
escalation vulnerabilities in the past.
We can safely leave user namespaces on for privileged users, as root
already has root privileges, but if you're not running builds on your
machine and really want to minimize the kernel attack surface then you
can set security.allowUserNamespaces to false.
Note that Chrome's sandbox requires either unprivileged CLONE_NEWUSER or
setuid, and Firefox's silently reduces the security level if it isn't
allowed (see about:support), so desktop users may want to set:
boot.kernel.sysctl."kernel.unprivileged_userns_clone" = true;
* nixos/k3s: simplify config expression
* nixos/k3s: add config assertions and trim unneeded bits
* nixos/k3s: add a test that k3s works; minor module improvements
This is a single-node test. Eventually we should also have a multi-node
test to verify the agent bit works, but that one's more involved.
* nixos/k3s: add option description
* nixos/k3s: add defaults for token/serveraddr
Now that the assertion enforces their presence, we dont' need to use the typesystem for it.
* nixos/k3s: remove unneeded sudo in test
* nixos/k3s: add to test list
After the recent rewrite, enabled extensions are passed to php programs
through an extra ini file by a wrapper. Since httpd uses shared module
instead of program, the wrapper did not affect it and no extensions
other than built-ins were loaded.
To fix this, we are passing the extension config another way – by adding it
to the service's generated config.
For now we are hardcoding the path to the ini file. It would be nice to add
the path to the passthru and use that once the PHP expression settles down.
Add a distinctive `unit-script` prefix to systemd unit scripts to make
them easier to find in the store directory. Do not add this prefix to
actual script file name as it clutters logs.
Current journal output from services started by `script` rather than
`ExexStart` is unreadable because the name of the file (which journalctl
records and outputs) quite literally takes 1/3 of the screen (on smaller
screens).
Make it shorter. In particular:
* Drop the `unit-script` prefix as it is not very useful.
* Use `writeShellScriptBin` to write them because:
* It has a `checkPhase` which is better than no checkPhase.
* The script itself ends up having a short name.
systemd-tmpfiles will load all files in lexicographic order and ignores rules
for the same path in later files with a warning Since we apply the default rules
provided by systemd, we should load user-defines rules first so users have a
chance to override defaults.
This reverts commit 5532065d06.
As far as I can tell setting RemainAfterExit=true here completely breaks
certificate renewal, which is really bad!
the sytemd timer will activate the service unit every OnCalendar=,
however with RemainAfterExit=true the service is already active! So the
timer doesn't rerun the service!
The commit also broke the actual tests, (As it broke activation too)
but this was fixed later in https://github.com/NixOS/nixpkgs/pull/76052
I wrongly assumed that PR fixed renewal too, which it didn't!
testing renewals is hard, as we need to sleep in tests.
Without this, you can change the list of appended or prepended nameservers in
your NetworkManager config, and nixos-rebuild doesn't cause those changes to
come into effect.
For reasons yet unknown, the vxlan backend doesn't work (at least inside
the qemu networking), so this is moved to the udp backend.
Note changing the backend apparently also changes the interface name,
it's now `flannel0`, not `flannel.1`
fixes#74941
This was whitespace-sensitive, kept fighting with my editor and broke
the tests easily. To fix this, let python convert the output to
individual lines, and strip whitespace from them before comparing.
When trying to build a VM using `nixos-build-vms` with a configuration
that doesn't evaluate, an error "at `<unknown-file>`" is usually shown.
This happens since the `build-vms.nix` creates a VM-network of
NixOS-configurations that are attr-sets or functions and don't contain
any file information. This patch manually adds the `_file`-attribute to
tell the module-system which file contained broken configuration:
```
$ cat vm.nix
{ vm.invalid-option = 1; }
$ nixos-build-vms vm.nix
error: The option `invalid-option' defined in `/home/ma27/Projects/nixpkgs/vm.nix@node-vm' does not exist.
(use '--show-trace' to show detailed location information)
```
This commit:
1. Updates the path of the traefik package, so that the out output is
used.
2. Adapts the configuration settings and options to Traefik v2.
3. Formats the NixOS traefik service using nixfmt.
Commit 1d2c3279311e4f03fcf164e1366f2fda9f4bfccf in the upstream kernel
repository removed support for the scalar x86_64 and i586 AES
assembly implementations, since the generic AES implementation generated
by the compiler is faster for both platforms. Remove the modules from
the cryptoModules list. This causes a regression for kernel versions
>=5.4 which include the removal. This should have no negative impact on
AES performance on older kernels since the generic implementation should
be faster there as well since the implementation was hardly touched from
its initial submission.
Fixes#84842
According to my analysis the last critical fix went into v5.4.23, I have
confirmed this by running WebGL over night and haven't seen a single
i915 GPU hang. Lets remove the notes from the release notes.
(cherry picked from commit da764d22ce3b698707861d58824843ded87cbb0a)
We already set the relevant env vars in the systemd services. That does
not help one when executing any of the executables outside a service,
e.g. when creating a new user.
we use stdenv.hostPlatform.uname.processor, which I believe is just like
`uname -p`.
Example values:
```
(import <nixpkgs> { system = "x86_64-linux"; }).stdenv.hostPlatform.uname.processor
"x86_64"
(import <nixpkgs> { system = "aarch64-linux"; }).stdenv.hostPlatform.uname.processor
aarch64
(import <nixpkgs> { system = "armv7l-linux"; }).stdenv.hostPlatform.uname.processor
"armv7l"
```
The new wording does not assume the user is upgrading.
This is because a user could be setting up a new installation on 20.03
on a server that has a 19.09 or before stateVersion!!
The new wording ensures that confusion is reduced by stating that they
do not have to care about the assumed 16→17 transition.
Then, the wording explains that they should, and how to upgrade to
version 18.
It also reviews the confusing wording about "multiple" upgrades.
* * *
The only thing we cannot really do is stop a fresh install of 17 if
there was no previous install, as it cannot be detected. That makes a
useless upgrade forced for new users with old state versions.
It is also important to state that they must set their package to
Nextcloud 18, as future upgrades to Nextcloud will not allow an uprade
from 17!
I assume future warning messages will exist specifically stating what to
do to go from 18 to 19, then 19 to 20, etc...
This allows to have multiple certificates with the same common name.
Lego uses in its internal directory the common name to name the certificate.
fixes#84409
This is an backward incompatible change from upstream dhcpcd [0], as
this could have easily locked me out of my box.
As dhcpcd doesn't allow to use only a blacklist (denyinterfaces in
dhcpcd.conf) of devices and use all remaining devices, while explicitly
allowing some interfaces like bridges, I think the best option would be
to not change anything about it and just educate the users here about
that edge case and how to solve it.

I've had Netdata crash on me sometimes. Rarely but more than once. And I lost days of data before I noticed.
Let's be nice and restart it on failures by default.
This properly supports the `supportedSystems` and
`limitedSupportedSystems` arguments of `release-combined.nix`.
Previously, evaluation would fail if `x86_64-linux` was not part either
of those, since the tested job always referenced the `x86_64-linux`
nixos tests (which won't exist in an aarch64-only eval).
Since the hydra configuration for the jobset`trunk-combined` has both
`aarch64-linux` and `x86_64-linux` as supported systems, this will make
aarch64 be part of the tested job on that jobset.
Also removed `pkgs.hydra-flakes` since flake-support has been merged
into master[1]. Because of that, `pkgs.hydra-unstable` is now compiled
against `pkgs.nixFlakes` and currently requires a patch since Hydra's
master doesn't compile[2] atm.

Instead of making the configuration less portable by hard coding the number of
jobs equal to the cores we can also let nix set the same number at runtime.
This prevents duplication in cross-compiled nixos machines. The
bootstrapped glibc differs from the natively compiled one, so we get
two glibc’s in the closure. To reduce closure size, just use
stdenv.cc.libc where available.
Some changes might require manual migration steps:
"Due to changes to the way in which Gollum handles filenames, you may
have to change some links in your wiki when migrating from gollum 4.x.
See the release notes [0] for more details. You may find the
bin/gollum-migrate-tags script helpful to accomplish this. Also see the
--lenient-tag-lookup option for making tag lookup backwards compatible
with 4.x, though note that this will decrease performance on large wikis
with many tags." (source: [1])

As discussed in https://github.com/NixOS/nixpkgs/pull/73763, prevailing
consensus is to revert that commit. People use the hardened profile on
machines and run nix builds, and there's no good reason to use
unsandboxed builds at all unless you're in a platform that doesn't
support them.
This reverts commit 00ac71ab19.
So now we have only packages for human interaction in php.packages and
only extensions in php.extensions. With this php.packages.exts have
been merged into the same attribute set as all the other extensions to
make it flat and nice.
The nextcloud module have been updated to reflect this change as well
as the documentation.
In 7f838b4dde, we dropped systemd-udev-settle.service from display-manager.service's wants.
Unfortunately, we are doing something wrong since without it both Xorg and Wayland fail to start:
Failed to open gpu '/dev/dri/card0': GDBus.Error:org.freedesktop.DBus.Error.AccessDenied: Operation not permitted
Until we sort this out, let's add systemd-udev-settle.service to GDM to unblock the channels.
In contrast to `.service`-units, it's not possible to declare an
`overrides.conf`, however this is done by `generateUnits` for `.nspawn`
units as well. This change breaks the build if you have two derivations
configuring one nspawn unit.
This will happen in a case like this:
``` nix
{ pkgs, ... }: {
systemd.packages = [
(pkgs.writeTextDir "etc/systemd/nspawn/container0.nspawn" ''
[Files]
Bind=/tmp
'')
];
systemd.nspawn.container0 = {
/* ... */
};
}
```
This allows you to specify the system-wide flake registry. One use is
to pin 'nixpkgs' to the Nixpkgs version used to build the system:
nix.registry.nixpkgs.flake = nixpkgs;
where 'nixpkgs' is a flake input. This ensures that commands like
$ nix run nixpkgs#hello
pull in a minimum of additional store paths.
You can also use this to redirect flakes, e.g.
nix.registry.nixpkgs.to = {
type = "github";
owner = "my-org";
repo = "my-nixpkgs";
};
Many options define their example to be a Nix value without using
literalExample. This sometimes gets rendered incorrectly in the manual,
causing confusion like in https://github.com/NixOS/nixpkgs/issues/25516
This fixes it by using literalExample for such options. The list of
option to fix was determined with this expression:
let
nixos = import ./nixos { configuration = {}; };
lib = import ./lib;
valid = d: {
# escapeNixIdentifier from https://github.com/NixOS/nixpkgs/pull/82461
set = lib.all (n: lib.strings.escapeNixIdentifier n == n) (lib.attrNames d) && lib.all (v: valid v) (lib.attrValues d);
list = lib.all (v: valid v) d;
}.${builtins.typeOf d} or true;
optionList = lib.optionAttrSetToDocList nixos.options;
in map (opt: {
file = lib.elemAt opt.declarations 0;
loc = lib.options.showOption opt.loc;
}) (lib.filter (opt: if opt ? example then ! valid opt.example else false) optionList)
which when evaluated will output all options that use a Nix identifier
that would need escaping as an attribute name.
This windowManager and desktopManager doesn't even have
an option to use it. git history suggests to me that there's no way anyone
finds this useful anymore.

This option allows replacing the tmpfs mounted on / by
the live CD's init script with a physical device
Since nixOS symlinks everything there's no trouble
at all.
That enables the user to easily use a nixOS live CD
as a portable installation.
Note that due to some limitations in how the store is mounted
currently only the non-store things are persisted.
Upgrades Hydra to the latest master/flake branch. To perform this
upgrade, it's needed to do a non-trivial db-migration which provides a
massive performance-improvement[1].
The basic ideas behind multi-step upgrades of services between NixOS versions
have been gathered already[2]. For further context it's recommended to
read this first.
Basically, the following steps are needed:
* Upgrade to a non-breaking version of Hydra with the db-changes
(columns are still nullable here). If `system.stateVersion` is set to
something older than 20.03, the package will be selected
automatically, otherwise `pkgs.hydra-migration` needs to be used.
* Run `hydra-backfill-ids` on the server.
* Deploy either `pkgs.hydra-unstable` (for Hydra master) or
`pkgs.hydra-flakes` (for flakes-support) to activate the optimization.
The steps are also documented in the release-notes and in the module
using `warnings`.
`pkgs.hydra` has been removed as latest Hydra doesn't compile with
`pkgs.nixStable` and to ensure a graceful migration using the newly
introduced packages.
To verify the approach, a simple vm-test has been added which verifies
the migration steps.

After upgrading to NixOS 20.03, I've got the following warning:
nginx: [warn] could not build optimal types_hash, you should increase either types_hash_max_size: 2048 or types_hash_bucket_size: 64; ignoring types_hash_bucket_size
The documentation states that "if nginx emits the message requesting
to increase either hash max size or hash bucket size then the first
parameter should first be increased" (aka types_hash_max_size).
In 19.03, the size of mime.types was around 100 entries. In 20.03, we
are around 900 entries. This is due to ff0148d868 which makes nginx
use mailcap mime.types.
In ff0148d868, nginx configuration was modified to use mime.types
from mailcap package as it is more complete. However, there are two
places where mime.types is included in configuration. When the user
was setting `cfg.httpConfig`, the mime.types from nginx was still
used. This commit fix that by moving the common snippet in a variable
of its own and ensure it is used at both places.
While our ETag patch works pretty fine if it comes to serving data off
store paths, it unfortunately broke something that might be a bit more
common, namely when using regexes to extract path components of
location directives for example.
Recently, @devhell has reported a bug with a nginx location directive
like this:
location ~^/\~([a-z0-9_]+)(/.*)?$" {
alias /home/$1/public_html$2;
}
While this might look harmless at first glance, it does however cause
issues with our ETag patch. The alias directive gets broken up by nginx
like this:
*2 http script copy: "/home/"
*2 http script capture: "foo"
*2 http script copy: "/public_html/"
*2 http script capture: "bar.txt"
In our patch however, we use realpath(3) to get the canonicalised path
from ngx_http_core_loc_conf_s.root, which returns the *configured* value
from the root or alias directive. So in the example above, realpath(3)
boils down to the following syscalls:
lstat("/home", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
lstat("/home/$1", 0x7ffd08da6f60) = -1 ENOENT (No such file or directory)
During my review[1] of the initial patch, I didn't actually notice that
what we're doing here is returning NGX_ERROR if the realpath(3) call
fails, which in turn causes an HTTP 500 error.
Since our patch actually made the canonicalisation (and thus additional
syscalls) necessary, we really shouldn't introduce an additional error
so let's - at least for now - silently skip return value if realpath(3)
has failed.
However since we're using the unaltered root from the config we have
another issue, consider this root:
/nix/store/...-abcde/$1
Calling realpath(3) on this path will fail (except if there's a file
called "$1" of course), so even this fix is not enough because it
results in the ETag not being set to the store path hash.
While this is very ugly and we should fix this very soon, it's not as
serious as getting HTTP 500 errors for serving static files.
I added a small NixOS VM test, which uses the example above as a
regression test.
It seems that my memory is failing these days, since apparently I *knew*
about this issue since digging for existing issues in nixpkgs, I found
this similar pull request which I even reviewed:
https://github.com/NixOS/nixpkgs/pull/66532
However, since the comments weren't addressed and the author hasn't
responded to the pull request, I decided to keep this very commit and do
a follow-up pull request.

It's impossible to move two major-versions forward when upgrading
Nextcloud. This is an issue when comming from 19.09 (using Nextcloud 16)
and trying to upgrade to 20.03 (using Nextcloud 18 by default).
This patch implements the measurements discussed in #82056 and #82353 to
improve the update process and to circumvent similar issues in the
future:
* `pkgs.nextcloud` has been removed in favor of versioned attributes
(currently `pkgs.nextcloud17` and `pkgs.nextcloud18`). With that
approach we can safely backport major-releases in the future to
simplify those upgrade-paths and we can select one of the
major-releases as default depending on the configuration (helpful to
decide whether e.g. `pkgs.nextcloud17` or `pkgs.nextcloud18` should be
used on 20.03 and `master` atm).
* If `system.stateVersion` is older than `20.03`, `nextcloud17` will be
used (which is one major-release behind v16 from 19.09). When using a
package older than the latest major-release available (currently v18),
the evaluation will cause a warning which describes the issue and
suggests next steps.
To make those package-selections easier, a new option to define the
package to be used for the service (namely
`services.nextcloud.package`) was introduced.
* If `pkgs.nextcloud` exists (e.g. due to an overlay which was used to
provide more recent Nextcloud versions on older NixOS-releases), an
evaluation error will be thrown by default: this is to make sure that
`services.nextcloud.package` doesn't use an older version by accident
after checking the state-version. If `pkgs.nextcloud` is added
manually, it needs to be declared explicitly in
`services.nextcloud.package`.
* The `nixos/nextcloud`-documentation contains a
"Maintainer information"-chapter which describes how to roll out new
Nextcloud releases and how to deal with old (and probably unsafe)
versions.
Closes#82056
Make it clear that the warning is that updatedb will run as root, not
that locate will only run as root. Also explain how to silence the
warning.

Dropbear lags behind OpenSSH significantly in both support for modern
key formats like `ssh-ed25519`, let alone the recently-introduced
U2F/FIDO2-based `sk-ssh-ed25519@openssh.com` (as I found when I switched
my `authorizedKeys` over to it and promptly locked myself out of my
server's initrd SSH, breaking reboots), as well as security features
like multiprocess isolation. Using the same SSH daemon for stage-1 and
the main system ensures key formats will always remain compatible, as
well as more conveniently allowing the sharing of configuration and
host keys.
The main reason to use Dropbear over OpenSSH would be initrd space
concerns, but NixOS initrds are already large (17 MiB currently on my
server), and the size difference between the two isn't huge (the test's
initrd goes from 9.7 MiB to 12 MiB with this change). If the size is
still a problem, then it would be easy to shrink sshd down to a few
hundred kilobytes by using an initrd-specific build that uses musl and
disables things like Kerberos support.
This passes the test and works on my server, but more rigorous testing
and review from people who use initrd SSH would be appreciated!
Running the manual on a TTY is useless in the graphical ISOs and not
particularly useful in non-graphical ISOs (since you can also run
'nixos-help').

* Removed the use of gnome-screensaver (https://gitlab.gnome.org/GNOME/gnome-flashback/issues/18)

While renaming `networking.defaultMailServer` directly to
`services.ssmtp` is shorter and probably clearer, it causes eval errors
due to the second rename (directDelivery -> enable) when using e.g. `lib.mkForce`.
For instance,
``` nix
{ lib, ... }: {
networking.defaultMailServer = {
hostName = "localhost";
directDelivery = lib.mkForce true;
domain = "example.org";
};
}
```
would break with the following (rather confusing) error:
```
error: The option value `services.ssmtp.enable' in `/home/ma27/Projects/nixpkgs/nixos/modules/programs/ssmtp.nix' is not of type `boolean'.

Previously, the NixOS ACME module defaulted to using P-384 for
TLS certificates. I believe that this is a mistake, and that we
should use P-256 instead, despite it being theoretically
cryptographically weaker.
The security margin of a 256-bit elliptic curve cipher is substantial;
beyond a certain level, more bits in the key serve more to slow things
down than add meaningful protection. It's much more likely that ECDSA
will be broken entirely, or some fatal flaw will be found in the NIST
curves that makes them all insecure, than that the security margin
will be reduced enough to put P-256 at risk but not P-384. It's also
inconsistent to target a curve with a 192-bit security margin when our
recommended nginx TLS configuration allows 128-bit AES. [This Stack
Exchange answer][pornin] by cryptographer Thomas Pornin conveys the
general attitude among experts:
> Use P-256 to minimize trouble. If you feel that your manhood is
> threatened by using a 256-bit curve where a 384-bit curve is
> available, then use P-384: it will increases your computational and
> network costs (a factor of about 3 for CPU, a few extra dozen bytes
> on the network) but this is likely to be negligible in practice (in a
> SSL-powered Web server, the heavy cost is in "Web", not "SSL").
[pornin]: https://security.stackexchange.com/a/78624
While the NIST curves have many flaws (see [SafeCurves][safecurves]),
P-256 and P-384 are no different in this respect; SafeCurves gives
them the same rating. The only NIST curve Bernstein [thinks better of,
P-521][bernstein] (see "Other standard primes"), isn't usable for Web
PKI (it's [not supported by BoringSSL by default][boringssl] and hence
[doesn't work in Chromium/Chrome][chromium], and Let's Encrypt [don't
support it either][letsencrypt]).

[letsencrypt]: https://letsencrypt.org/docs/integration-guide/#supported-key-algorithms
So there's no real benefit to using P-384; what's the cost? In the
Stack Exchange answer I linked, Pornin estimates a factor of 3×
CPU usage, which wouldn't be so bad; unfortunately, this is wildly
optimistic in practice, as P-256 is much more common and therefore
much better optimized. [This GitHub comment][openssl] measures the
performance differential for raw Diffie-Hellman operations with OpenSSL
1.1.1 at a whopping 14× (even P-521 fares better!); [Caddy disables
P-384 by default][caddy] due to Go's [lack of accelerated assembly
implementations][crypto/elliptic] for it, and the difference there seems
even more extreme: [this golang-nuts post][golang-nuts] measures the key
generation performance differential at 275×. It's unlikely to be the
bottleneck for anyone, but I still feel kind of bad for anyone having
lego generate hundreds of certificates and sign challenges with them
with performance like that...

In conclusion, there's no real reason to use P-384 in general: if you
don't care about Web PKI compatibility and want to use a nicer curve,
then Ed25519 or P-521 are better options; if you're a NIST-fearing
paranoiac, you should use good old RSA; but if you're a normal person
running a web server, then you're best served by just using P-256. Right
now, NixOS makes an arbitrary decision between two equally-mediocre
curves that just so happens to slow down ECDH key agreement for every
TLS connection by over an order of magnitude; this commit fixes that.
Unfortunately, it seems like existing P-384 certificates won't get
migrated automatically on renewal without manual intervention, but
that's a more general problem with the existing ACME module (see #81634;
I know @yegortimoshenko is working on this). To migrate your
certificates manually, run:
$ sudo find /var/lib/acme/.lego/certificates -type f -delete
$ sudo find /var/lib/acme -name '*.pem' -delete
$ sudo systemctl restart 'acme-*.service' nginx.service
(No warranty. If it breaks, you get to keep both pieces. But it worked
for me.)
NixOS 20.03 is built on kernel 5.4 and 19.09 is on 4.19, so we should update
this option to the highest value possible, per linked upstream instructions from
Amazon.
* nixos/nixpkgs.nix: Allow just using config in system
This assertion requires system to work properly. We might not have
this in cases where the user just sets config and wants Nixpkgs to
infer system from that. This adds a default for when this happens,
using doubleFromSystem.
* parens
`$toplevel/system` of a system closure with `x86_64` kernel and `i686` userland should contain "x86_64-linux".
If `$toplevel/system` contains "i686-linux", the closure will be run using `qemu-system-i386`, which is able to run `x86_64` kernel on most Intel CPU, but fails on AMD.
So this fix is for a rare case of `x86_64` kernel + `i686` userland + AMD CPU
Previously, systemd.network.links was only respected with networkd
enabled, but it's really udev taking care of links, no matter if
networkd is enabled or not.
With our module fixed, there's no need to manually manage the text file
anymore.
This was originally applied in 3d1079a20d,
but was reverted due to 1115959a8d causing
evaluation errors on hydra.
This mirrors the behaviour of systemd - It's udev that parses `.link`
files, not `systemd-networkd`.
This was originally applied in 36ef112a47,
but was reverted due to 1115959a8d causing

The type of the checkReversePath option allows "strict" and "loose" as
well as boolean values.
If the host network stack is slow to start, the alertmanager fails to
start with this error message:
caller=main.go:256 msg="unable to initialize gossip mesh" err="create memberlist: Failed to get final advertise address: No private IP address found, and explicit IP not provided"
This bug can be reproduced by shutting down the network stack and
restarting the alertmanager.
Note I don't know why I didn't hit this issue with previous
alertmanager releases.
* Linkify all service options used in the code-examples.
* Demonstrated the use of `riot-web.override {}`.
* Moved the example how to configure a postgresql-database for
`matrix-synapse` to this document from the 20.03 release-notes.
Fixes some dependency ordering problems at boot time with services that
require DNS. Without Type=notify these services might be started before
stubby was ready to accept DNS requests.
The v7 series is very different.
This commit introduces the 3 packages: fahclient, fahcontrol and
fahviewer. It also rebuilds the NixOS module to map better with the new
client.
Previously the assertion passed if the kernel had support OR the
filter was *enabled*. In the case of a kernel without support, the
`checkReversePath` option defaulted to false, and then failed the
assertion.
...even when networkd is disabled
This reverts commit ce78f3ac70, reversing
changes made to dc34da0755.
I'm sorry; Hydra has been unable to evaluate, always returning
> error: unexpected EOF reading a line
and I've been unable to reproduce the problem locally. Bisecting
pointed to this merge, but I still can't see what exactly was wrong.
extraModprobeConfig could be applied too late i.e. if the driver has been
loaded in initrd, while the harddrive is still encrypted.
Using a kernelParams works in all cases however.
To quote the XDG specification:
There is a single base directory relative to which user-specific
data files should be written. This directory is defined by the\
environment variable $XDG_DATA_HOME.
Rather than adding another directory to $HOME, I think that it's better
to follow this standard to avoid a cluttered home-dir.
Running haproxy with "DynamicUser = true" doesn't really work, since
it prohibits specifying a TLS certificate bundle with limited
permissions. This revives the haproxy user and group, but makes them
dynamically allocated by NixOS, rather than statically allocated. It
also adds options to specify which user and group haproxy runs as.
Previously, systemd.network.links was only respected with networkd
enabled, but it's really udev taking care of links, no matter if

This is to facilitate units that should _only_ be manually started and
not activated when a configuration is switched to.
More specifically this is to be used by the new Nixops deploy-*
targets created in https://github.com/NixOS/nixops/pull/1245 that are
triggered by Nixops before/after switch-to-configuration is called.
When blocklists are built with a derivation, using extraHosts would
require IFD, since the result of the derivation needs to be converted to
a string again.
By introducing this option no IFD is needed for such use-cases, since
the fetched files can be assigned directly.
- Fix misspelled option. mkRenamedOptionModule is not used because the
option hasn't really worked before.
- Add missing cfg.telemetryPath arg to ExecStart.
- Fix mkdir invocation in test.
The allowed values have changed in bd3319d28c.
0.15:
--log.level="info" Only log messages with the given severity or above. Valid levels: [debug, info, warn, error, fatal]
--log.format="logger:stderr"
Set the log target and format. Example: "logger:syslog?appname=bob&local=7" or "logger:stdout?json=true"
0.17:
--log.level=info Only log messages with the given severity or above. One of: [debug, info, warn, error]
--log.format=logfmt Output format of log messages. One of: [logfmt, json]
This avoids a possible surprise if the user is using `nixpkgs.system`
and `nesting.children`. `nesting.children` is expected to ignore all
parent configuration so we shouldn't propagate the user-facing option
`nixpkgs.system`. To avoid doing so, we introduce a new internal
option for holding the value passed to eval-config.nix, and use that
when recursing for nesting.
Add a cage module to nixos. This can be used to make kiosk-style
systems that boot directly to a single application. The user (demo by
default) is automatically logged in by this service and the
program (xterm by default) is automatically started.
This is useful for some embedded, single-user systems where we want
automatic booting. To keep the system secure, the user should have
limited privileges.
Based on the service provided in the Cage wiki here:

* prometheus-nginx-exporter: 0.5.0 -> 0.6.0
* nixos/prometheus-nginx-exporter: update for 0.6.0
Added new option constLabels and updated virtualHost name in the
exporter's test.
Prior to this fix, changes to certain settings would not be applied
automatically and users would have to know to manually restart the
affected service. A prime example of this is
`services.mailman.hyperkitty.baseUrl`, or various things that affect
`mailman3/settings.py`
The current weekly setting causes every NixOS server to try to renew
its certificate at midnight on the dot on Monday. This contributes to
the general problem of periodic load spikes for Let's Encrypt; NixOS
is probably not a major contributor to that problem, but we can lead by
example by picking good defaults here.
The values here were chosen after consulting with @yuriks, an SRE at
Let's Encrypt:
* Randomize the time certificates are renewed within a 24 hour period.
* Check for renewal every 24 hours, to ensure the certificate is always
renewed before an expiry notice is sent out.
* Increase the AccuracySec (thus lowering the accuracy(!)), so that
systemd can coalesce the renewal with other timers being run.
(You might be worried that this would defeat the purpose of the time
skewing, but systemd is documented as avoiding this by picking a
random time.)
The environment.systemPackages option lacks in the example which is used in the next paragraph to explain merging of the options defined by multiple modules.
This is useful when buildLayeredImage is called in a generic way
that should allow simple (base) images to be built, which may not
reference any store paths.
The current behavior lets `system` default to
`builtins.currentSystem`. The system value specified to
`eval-config.nix` has very low precedence, so this should compose
properly.
Fixes#80806
I am not sure how this ever passed on hydra but 30s is barely enough to
pass the configure phase of opensmtpd. It is likely the package was
built as part of another jobset. Whenever it is built as part of the
test execution the timeout propagates and 30s is clearly not enough for
that.
On servers especially, phantomjs2 pulls graphical dependencies which is unecessary.
This pathes enable the package to be linked/installed without
phantomjs2. Phantomjs2 is disabled by default since it has been deprecated in grafana https://grafana.com/docs/grafana/latest/guides/whats-new-in-v6-4/
The subtest was mainly written to demonstrate the VRF-issues with a
5.x-kernel. However this breaks the entire test now as we have 5.4 as
default kernel. Disabling the test for now, I still need to find some
time to investigate.
Directory mode 755 is standard for running services. Without this,
downloadDirPermissions doesn't have any use since other users can't even
look inside the main transmission directory
* nixos/gdm: Fix pulseaudio tmpfiles structure

Note we're not using wayland default in the graphical media because it
could cause headaches for Nvidia users. But the session is still available
if someone logs out.
lego already bundles the chain with the certificate,[1] so the current
code, designed for simp_le, was resulting in duplicate certificate
chains, manifesting as "Chain issues: Incorrect order, Extra certs" on
the Qualys SSL Server Test.
cert.pem stays around as a symlink for backwards compatibility.

It was added in PR #79786 (7a625e7) and then removed in commit 2de3caf
(apparently unintentionally as a rebase conflict).
_I think the ordering used by Eelco would sort the line this way._
