This will make the list much easier to re-use, eg. for `nixosTests` The drawback is that this approaches makes the ``` nix-build release.nix -A tests.opensmtpd.x86_64-linux ``` command about twice as slow (3s to 6s): it now has to evaluate `nixpkgs` once for each architecture, instead of just having the hardcoded list of tests that allowed to say “ok just evaluate for x86_64-linux”. On the other hand, complete evaluation of `release.nix` should be much faster because we no longer import `nixpkgs` for each test: testing with the following command went from 30s to 18s, and that's just for a few tests. ``` time nix-instantiate --eval --strict nixos/release.nix -A tests.nat ``` I initially wanted to test on the whole `release.nix`, but there are too many broken tests and it takes too long to eval them all, especially compared to the fact that the current implementation breaks some setup. Given developers can just `nix-build nixos/tests/my-test.nix`, it sounds like an overall win. |
