How to share a base home-manager config via Git submodule?

Help
1

I want to share a base home-manager configuration across multiple systems. I prefer to use Git submodule in this case. Unfortunately, it does not work …

flake.nix of main Git repository:

{
  description = "Home Manager configuration";

  inputs = {
    nixpkgs.url = "github:nixos/nixpkgs/nixos-unstable";
    home-manager = {
      url = "github:nix-community/home-manager";
      inputs.nixpkgs.follows = "nixpkgs";
    };
    base = {
      url = "git+file:./base";
      flake = false;
    };
  };

  outputs = { nixpkgs, home-manager, base, ... }@inputs:
  let
    system = "x86_64-linux";
  in
  {
    defaultPackage.x86_64-linux = home-manager.defaultPackage.x86_64-linux;

    homeConfigurations = home-manager.lib.homeManagerConfiguration {
      pkgs = nixpkgs.legacyPackages.${system};

      modules = [
        ./home.nix
        base
      ];
    };
};

default.nix in submodule

{ config, pkgs, lib, ... }:

{
  home.packages = with pkgs; [
    k9s
  ];
}

Error:

error: The option `dirtyRev' does not exist. Definition values:

How can I fix this issue?
Thanks in Advance!

Try using either ./base or base.outPath

Thanks!

base.outPath is working :+1:

Part of my corrected flake.nix:

# snip
  outputs = { nixpkgs, home-manager, base, ... }@inputs:
  let
    system = "x86_64-linux";
  in
  {
    defaultPackage.x86_64-linux = home-manager.defaultPackage.x86_64-linux;

    homeConfigurations = home-manager.lib.homeManagerConfiguration {
      pkgs = nixpkgs.legacyPackages.${system};

      modules = [
        base.outPath
        ./home.nix
      ];
    };
# snip
