Correct way to package a grub .tar theme

Help
1

I want to package a nixos grub theme, this is what i have right now, i need to extract themes/nixos.tar to $out, this is what i have and it isnt working:

{pkgs, ...}:
pkgs.stdenv.mkDerivation rec {
  pname = "nixos-distro-theme";
  version = "v3.2";
  src = pkgs.fetchFromGitHub {
    owner = "AdisonCavani";
    repo = "distro-grub-themes";
    rev = version;
    hash = "sha256-ZcoGbbOMDDwjLhsvs77C7G7vINQnprdfI37a9ccrmPs=";
  };
  installPhase = ''
    tar -xf themes/nixos.tar -C $out
  '';
}

Overall, the problem is you’re trying to execute a directory, which isn’t a binary, you’d need to use lib.getExe pkgs.gnutar. But in this case, just use tar -xf ... since GNU tar is already part of stdenv:

how did i forget that, stupid mistake… used tar instead of ${pkgs.gnutar} but got this:

nix build .#nixos-grub

You may need to add: mkdir -p $out
