[question]: How to build container from flakified devenv?

[gabyx]

This project is really cool!.
I am however running into the need to build a OCI container from a flakeified devenv - devShell?

inputs.devenv.lib.mkShell {
  inherit pkgs inputs;
  modules = [
    (
      { pkgs, config, ... }:
      {
        packages = [
          pkgs.${namespace}.bootstrap
          pkgs.${namespace}.treefmt
        ];
      }
    )
  ];
}

I have that in my outputs devShell.default and could also put that into a package packages.defaultShell:

How can I build a container from this? Is there a best-practice way to do it?

Thanks a lot!
