Simple and flat. System in system/, user in home-manager/.

Edit files in home-manager/programs/ then rebuild.

Edit home-manager/julien/default.nix then rebuild.

Edit configuration.nix or files in system/ then rebuild.

Check for errors:

nix flake check

Rollback:

sudo nixos-rebuild switch --rollback

List generations:

sudo nix-env --list-generations --profile /nix/var/nix/profiles/system

Clean old generations:

sudo nix-collect-garbage --delete-older-than 7d

If you have different screens, adapt the Kanshi configuration in home-manager/programs/kanshi.nix.

Get screen info:

wlr-randr

Copy the output info (criteria, mode, position, scale) into your Kanshi profiles. Example:

{
  profile.name = "your-setup";
  profile.outputs = [
    {
      criteria = "Your Monitor Brand Model Serial";
      scale = 1.0;
      mode = "[email protected]";
      position = "0,0";
      status = "enable";
    }
  ];
}

Then rebuild.

• Auto-login enabled (getty)
• Sudo without password for wheel group
• Docker disabled by default (use don/doff commands)
• Xanmod kernel for better performance
