systemd: Update to latest NixOS branch Updated to the latest version of the nixos-v237 branch, which fixes two things: * Make sure that systemd looks in /etc for configuration files. https://github.com/NixOS/systemd/pull/15 * Fix handling of the x-initrd.mount option. https://github.com/NixOS/systemd/pull/16 I've added NixOS VM tests for both to ensure we won't run into regressions. The newly added systemd test only tests for that and is by no means exhaustive, but it's a start. Personally I only wanted to fix the former issue, because that's the one I've been debugging. After sending in a pull request for our systemd fork (https://github.com/NixOS/systemd/pull/17) I got a notice from @Mic92, that he already fixed this and his fix was even better as it's even suitable for upstream (so we hopefully can drop that patch someday). The reason why the second one came in was simply because it has been merged before the former, but I thought it would be a good idea to have tests for that as well. In addition I've removed the sysconfdir=$out/etc entry to make sure the default (/etc) is used. Installing is still done to $out, because those directories that were previously into sysconfdir now get into factoryconfdir. Quote from commit NixOS/systemd@98067cc806ae0d2759cdd2334f230cd8548e531: By default systemd should read all its configuration from /etc. Therefore we rely on -Dsysconfdir=/etc in meson as default value. Unfortunately this would also lead to installation of systemd's own configuration files to `/etc` whereas we are limited to /nix/store. To counter that this commit introduces two new configuration variables `factoryconfdir` and `factorypkgconfdir` to install systemd's own configuration into nix store again, while having executables looking up files in /etc. Tested this change against all of the NixOS VM tests we have in nixos/release.nix. Between this change and its parent no new tests were failing (although a lot of them were flaky).
