    # Notes
      /*
        $ nix build .#nixosConfigurations.<hostname>.config.system.build.toplevel
          should let me build the system config without calling "nixos-rebuild"

        $ nix build .#nixosConfigurations.nixos-wsl.config.system.build.toplevel
          should let me build the "nixos-wsl" system config.

        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

        How to use config in an install:
          Mount partitions.
          $ sudo nixos-install -v --root /mnt --flake "github:Whovian9369/whovian_nixos_config#CONFIG_NAME"
        Example for nixosConfigurations.piplup:
          $ sudo nixos-install -v --root /mnt --flake "github:Whovian9369/whovian_nixos_config#piplup"
