Suites

Suites provide a mechanism for users to easily combine and name collections of profiles.

suites are defined in the importables argument in either the home or nixos namespace. They are a special case of an importable which is passed as a special argument (one that can be use in an imports line) to your hosts. All lists defined in suites are flattened and type-checked as paths.

Definition

rec {
  workstation = [ profiles.develop profiles.graphical users.nixos ];
  mobileWS = workstation ++ [ profiles.laptop ];
}

Usage

hosts/my-laptop.nix:

{ suites, ... }:
{
  imports = suites.mobileWS;
}
