ci seems to fail

[stepbrobd]

maybe need to bump the pinned nixpkgs version (im on nixpkgs-unstable)

[stepbrobd]

nvm, already addressed (you are too fast!)

Can you please reevaluate this?
I'm getting this error:

      error: attribute 'target' missing
       at /nix/store/ynalml2mdvvnjwvivy5v299qf4d8z33i-source/modules/system/boot/loader/raspberrypi/default.nix:537:49:
          536|             if lib.versionAtLeast lib.trivial.release "26.05" then
          537|               config.boot.kernelPackages.kernel.target
             |                                                 ^
          538|             else

while bumping this Repo to nixos-unstable or 26.05 with this patch is applied. Reverting the commits fixes it,

I'm unsure how config.boot.kernelPackages.kernel could ever have a target attribute. (It points to a Derivation)

I'd suggest reverting this until we better know what causes the original issue.

@tillob should be fixed in #199
