  /*
   * Evaluate a NixOS configuration using this evaluation of Nixpkgs.
   *
   * With this function you can write, for example, a package that
   * depends on a custom virtual machine image.
   *
   * Parameter: A module, path or list of those that represent the
   *            configuration of the NixOS system to be constructed.
   *
   * Result:    An attribute set containing packages produced by this
   *            evaluation of NixOS, such as toplevel, kernel and
   *            initialRamdisk.
   *            The result can be extended in the modules by defining
   *            extra options in system.build.
   *
   * Unlike in plain NixOS, the nixpkgs.config, nixpkgs.overlays and
   * nixpkgs.system options will be ignored by default. Instead,
   * nixpkgs.pkgs will have the default value of pkgs as it was
   * constructed right after invoking the nixpkgs function (e.g. the
   * value of import <nixpkgs> { overlays = [./my-overlay.nix]; }
   * but not the value of (import <nixpkgs> {} // { extra = ...; }).
   *
   * If you do want to use the config.nixpkgs options, you are
   * probably better off by calling nixos/lib/eval-config.nix
   * directly, even though it is possible to set config.nixpkgs.pkgs.
   *
   * For more information about writing NixOS modules, see
   * https://nixos.org/nixos/manual/index.html#sec-writing-modules
   *
   * Note that you will need to have called Nixpkgs with the system
   * parameter set to the right value for your deployment target.
