Changes the evaluation order in that it evaluates assertions before
warnings, so that eg. the following would work:
{ config, lib, ... }:
{
options.foo = lib.mkOption {
type = lib.types.bool;
default = true;
description = "...";
};
options.bar = lib.mkOption {
type = lib.types.bool;
default = false;
description = "...";
};
config = lib.mkMerge [
(lib.mkIf config.bar {
system.build.bar = "foobar";
})
(lib.mkIf config.foo {
assertions = lib.singleton {
assertion = config.bar;
message = "Bar needs to be enabled";
};
systemd.services.foo = {
description = "Foo";
serviceConfig.ExecStart = config.system.build.bar;
};
})
];
}
This is because the systemd module includes definitions for warnings
that would trigger evaluation of the config.system.build.bar definition.
The original pull request references a breakage due to the following:
{
services.nixosManual.enable = false;
services.nixosManual.showManual = true;
}
However, changing the eval order between asserts and warnings clearly is
a corner case here and it only happens because of the aforementioned
usage of warnings in the systemd module and needs more discussion.
Nevertheless, this is still useful because it lowers the evaluation time
whenever an assertion is hit, which is a hard failure anyway.
or else at least the following config will fail with an evaluation error
instead of an assert
```
{
services.nixosManual.enable = false;
services.nixosManual.showManual = true;
}
```
This fixes an issue with shells like fish that are not fully POSIX
compliant. The syntax `ENV=val cmd' doesn't work properly in there.
This issue has been addressed in #45932 and #45945, however it has been
recommended to use a single shell (`stdenv.shell' which is either
`bash' or `sh') to significantly reduce the maintenance overload in the
future.

Although double '/' in paths is not a problem for GRUB supplied with nixpkgs, sometimes NixOS's grub.conf read by external GRUB and there are versions of GRUB which fail
The instructions to install nixos behind a proxy were not clear. While
one could guess that setting http_proxy variables can get the install
rolling, one could end up with an installed system where the proxy
settings for the nix-daemon are not configured.
This commit updates the documentation with
1. steps to install behind a proxy
2. configure the global proxy settings so that nix-daemon can access
internet.
3. Pointers to use nesting.clone in case one has to use different proxy
settings on different networks.
The background color option is self-explanatory.
The mode is either `normal` or `stretch`, they are as defined by GRUB,
where normal will put the image in the top-left corner of the menu, and
stretch is the default, where it stretches the image without
consideration for the aspect ratio.

When rebuilding you have to manually run `systemctl --user
daemon-reload`. It gathers all authenticated users using
`loginctl list-user` and runs `daemon-reload` for each of them.
This is a first step towards a `nixos-rebuild` which is able to reload
user units from systemd. The entire task is fairly hard, however I
consider this patch usable as it allows to restart units without running
`daemon-reload` for each authenticated user.
This fixes an issue where setting both
`boot.loader.systemd-boot.editor` to `false` and
`boot.loader.systemd-boot.consoleMode` to any value would concatenate
the two configuration lines in the output, resulting in an invalid
`loader.conf`.
From reading the source I'm pretty sure it doesn't support multiple Yubikeys, hence
those options are useless.
Also, I'm pretty sure nobody actually uses this feature, because enabling it causes
extra utils' checks to fail (even before applying any patches of this branch).
As I don't have the hardware to test this, I'm too lazy to fix the utils, but
I did test that with extra utils checks commented out and Yubikey
enabled the resulting script still passes the syntax check.
Also reuse common cryptsetup invocation subexpressions.
- Passphrase reading is done via the shell now, not by cryptsetup.
This way the same passphrase can be reused between cryptsetup
invocations, which this module now tries to do by default (can be
disabled).
- Number of retries is now infinity, it makes no sense to make users
reboot when they fail to type in their passphrase.
This allows a developer to better identify in which snippet the
failure happened. Furthermore, users seeking help will have more
information available about the failure.
