just trying to build the image from the flake, getting:

> nix build --no-write-lock-file 'github:Mic92/nixos-aarch64-images#rockPro64'
error: fixed output derivation 'nixos-sd-image-23.11.5541.56528ee42526-aarch64-linux.img.zst' is not allowed to refer to other store paths.
       You may need to use the 'unsafeDiscardReferences' derivation attribute, see the manual for more details.

The error message is right, we need something, like:

https://github.com/nix-community/nix-index-database/pull/103/files#diff-206b9ce276ab5971a2489d75eb1b12999d4bf3843b7988cbe8d687cfde61dea0R33

Could you try to add this? I currently don't have the hardware around for testing.

@Mic92 Im not entirely sure where to put it. I tried doing the same thing as the example, using overrideAttrs on the one fetchUrl, as well as putting __structuredAttrs = true; unsafeDiscardReferences.out = true; directly in the mkDerivation attrsets, with the first leading to an eval error and the second having no effect. (Ive configured nixos before, but never packaged anything, so I have very little idea of what im doing.)

If you want to make a branch, id be happy to test any changes for you on a rockpro64.
