Adding template overrides allows for custom behavior for specific
instances of a template. Previously, it was not possible to provide
bind mounts for systemd-nspawn. This change allows it.
This adds a new internal option, services.slurm.etcSlurm such
that other modules can access slurm's config files. This is
needed, for example, when a service wants to run a slurm command.
When using `buildLayeredImage`, it is not possible to specify an image
name of the form `<registry>/my/image`, although it is a valid name.
This is due to derivations under `buildLayeredImage` using that image
name as their derivation name, but slashes are not permitted in that
context.
A while ago, #13099 fixed that exact same problem in `buildImage` by
using `baseNameOf name` in derivation names instead of `name`. This
change does the same thing for `buildLayeredImage`.
This is a major rewrite of the Privoxy module:
- As per RFC0042, remove privoxy.extraConfig and replace it
with a privoxy.settings option, which maps a NixOS freeform
submodule to the Privoxy configuration format.
- Move all top-level options that mirrored a setting to
the real ones in privoxy.settings. This still keeps the
type-checking, default values and examples in places.
- Add two convenience options: userActions and userFilters, which
simplify the operation of creating a file with pkgs.writeText,
converting it to a string and adding it to the actionsfile/
filterfile list.
- Add a privoxy.inspectHttps option to automagically setup TLS
decryption support. I don't know how long have been waiting
for this feature: can't believe it has just happened.
- Also add a privoxy.certsLifetime to control the periodical
cleanup of the temporary certificates generate by Privoxy.
Currently, kernel config options whose value is "yes" always override
options whose value is "no".
This is not always desired.
Generally speaking, if someone defines an option to have the value
"no", presumably they are disabling the option for a reason, so it's
not always OK to silently enable it due to another, probably unrelated
reason.
For example, a user may want to reduce the kernel attack surface and
therefore may want to disable features that are being enabled in
common-config.nix.
In fact, common-config.nix was already silently enabling options that
were intended to be disabled in hardened/config.nix for security
reasons, such as INET_DIAG.
By eliminating the custom merge function, these config options will
now use the default module option merge functions which make sure
that all options with the highest priority have the same value.
A user that wishes to override an option defined in common-config.nix
can currently use mkForce or mkOverride to do so, e.g.:
BINFMT_MISC = mkForce (option no);
That said, this is not going to be necessary in the future, because
the plan is for kernel config options defined in nixpkgs to use a
lower priority by default, like it currently happens for other module
options.
