        How to build ISO:
          Building .#nixosConfigurations.isoimage-pc.config.system.build.isoImage
            should build ISO to "result" (or other set) symlink.
          Alternatively, use:
          - nix build -L .#packages.x86_64-linux.build_isoimage-pc
          - nix build -L .#build_isoimage-pc
