  /* 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 attributes in system.build.
                Alternatively, you may use the result's config and
                options attributes to query any option.

     Example:

         let
           myOS = pkgs.nixos ({ lib, pkgs, config, ... }: {

             config.services.nginx = {
               enable = true;
               # ...
             };

             # Use config.system.build to exports relevant parts of a
             # configuration. The runner attribute should not be
             # considered a fully general replacement for systemd
             # functionality.
             config.system.build.run-nginx = config.systemd.services.nginx.runner;
           });
         in
           myOS.run-nginx

     Unlike in plain NixOS, the nixpkgs.config 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.

   * letting NixOS invoke Nixpkgs again. If a test machine needs to
