How to test on NixOS

For flakes enabled system, you can also try bobby285271/test-pantheon.

1. Clone the NixOS/nixpkgs repository and checkout to this PR, you can use the GitHub CLI tool gh.

$ gh repo clone NixOS/nixpkgs
$ cd nixpkgs
$ gh pr checkout 154475

2. Save the following NixOS configuration file as configuration.nix, you can save the file to any directory.

{ modulesPath, pkgs, config, ... }: {
  imports = [
    "${modulesPath}/virtualisation/qemu-vm.nix"
  ];

  environment.enableDebugInfo = true;
  services.xserver = {
    enable = true;
    layout = "us";
    desktopManager.pantheon.enable = true;
    desktopManager.pantheon.debug = true;
  };

  users.mutableUsers = false;

  users.extraUsers.test = {
    isNormalUser = true;
    uid = 1000;
    extraGroups = [ "wheel" "networkmanager" ];
    password = "test";
  };
  nixpkgs.config.allowAliases = false;

  virtualisation.qemu.options = [ "-device intel-hda -device hda-duplex" ];
  virtualisation.memorySize = 2048;
  virtualisation.diskSize = 8192;
}

3. Run the following command to build the packages and create a virtual machine with the above configuration. Do not forget to adjust the path to the nixpkgs checkout (/path/to/nixpkgs) and the configuration (/path/to/configuration.nix). It will take some time to build the packages, so grab some coffee while waiting.

$ env NIX_PATH=nixpkgs=/path/to/nixpkgs:nixos-config=/path/to/configuration.nix nixos-rebuild build-vm

4. You should see a message like this, run the command provided by the output:

Done. The virtual machine can be started by running /nix/store/...-nixos-vm/bin/run-nixos-vm

5. A QEMU virtual machine will be launched, wait for LightDM to start and login with the password test.

6. Test the upgrade and if you find anything wrong, please also try reproduce the issue on master then comment here with your findings so we can handle that properly (i.e. we will drop the commit here that introduces major regressions).
