* Flatpak
Here’s the =nixos.flatpak= module, enabling Flatpak itself and
optionally pulling in its builder for the rare occasion I want to
build a Flatpak myself.
#+begin_src nix :tangle yes
{
  flake.modules.nixos.flatpak = {
    pkgs,
    lib,
    config,
    ...
  }:
    with lib; let
      cfg = config.mySystem.packages.flatpak;
    in {
      <<enable-flatpak>>
      <<builder>>
    };
}
#+end_src

** Enabling Flatpak
Flatpak support itself is always on once this module is imported.
#+name: enable-flatpak
#+begin_src nix
config.services.flatpak.enable = true;
#+end_src

** Flatpak Builder
=flatpak-builder= is only worth installing on the machines where I
actually build Flatpaks, if any, so it stays behind its own toggle.
#+name: builder
#+begin_src nix
options.mySystem.packages.flatpak.builder.enable = mkEnableOption "Enable Flatpak builder";
config.environment.systemPackages = lists.optional cfg.builder.enable pkgs.flatpak-builder;
#+end_src
