1. This makes aggregates of submodules (including the very important
"nixos-option users.users.<username>" case) behave the same way as any
other you-need-to-keep-typing-to-get-to-an-option-leaf (eg:
"nixos-option environment").
Before e0780c5:
$ nixos-option users.users.root
error: At 'root' in path 'users.users.root': Attribute not found
An error occurred while looking for attribute names. Are you sure that 'users.users.root' exists?
After e0780c5 but before this change, this query just printed out a raw
thing, which is behavior that belongs in "nix eval", "nix-instantiate
--eval", or "nix repl <<<":
$ nixos-option users.users.root
{
_module = {
args = { name = "root"; };
check = true;
};
createHome = false;
cryptHomeLuks = null;
description = "System administrator";
...
After this change:
$ nixos-option users.users.root
This attribute set contains:
createHome
cryptHomeLuks
description
extraGroups
group
hashedPassword
...
2. For aggregates of other types (not submodules), print out the option
that contains them rather than printing an error message.
Before:
$ nixos-option environment.shellAliases.l
error: At 'l' in path 'environment.shellAliases.l': Attribute not found
An error occurred while looking for attribute names. Are you sure that 'environment.shellAliases.l' exists?
After:
$ nixos-option environment.shellAliases.l
Note: showing environment.shellAliases instead of environment.shellAliases.l
Value:
{
l = "ls -alh";
ll = "ls -l";
ls = "ls --color=tty";
}
...
Deperecates the interfaces option which was used to generate a host:port
list whereas the port was always hardcoded to 53. This unifies the
listen configuration for plain and TLS sockets and allows to specify a
port without an address for wildcard binds.
Systemd dependencies for scripted mode
were refactored according to analysis in #34586.
networking.vswitches can now be used with systemd-networkd,
although they are not supported by the daemon, a nixos receipe
creates the switch and attached required interfaces (just like
the scripted version).
Vlans and internal interfaces are implemented following the
template format i.e. each interface is
described using an attributeSet (vlan and type at the moment).
If vlan is present, then interface is added to the vswitch with
given tag (access mode). Type internal enabled vswitch to create
interfaces (see openvswitch docs).
Added configuration for configuring supported openFlow version on
the vswitch
This commit is a split from the original PR #35127.
This makes ~2.5x speed up of an empty container instantiate, hence reduces
rebuild time of system with many declarative containers.
Note that this doesn't affect production systems much, becaseu those most
likely already include `minimal.nix` profile.
The upstream session files display managers use have no concept of sessions being composed from
desktop manager and window manager. To be able to set upstream session files as default
session, we need a single option. Having two different ways to set default session would be confusing,
though, so we decided to deprecate the old method.
We also created separate script for each session, just like we already had a separate desktop
file for each one, and started using displayManager.sessionPackages mechanism to make the
session handling more uniform.
There's two ways of providing graphical sessions now:
- `displayManager.session` via. `desktopManager.session` and
`windowManager.session`
- `displayManager.sessionPackages`
`sessionPackages` doesn't make a distinction between desktop and window
managers. This makes selecting a session provided by a package using
`desktopManager.default` nonsensical.
We therefor introduce `displayManager.defaultSession` which can select a session
from either `displayManager.session` or `displayManager.sessionPackages`.
It will default to `desktopManager.default + windowManager.default` as before.
If the dm default is "none" it will select the first provided session from
`sessionPackages`.
