+  /* 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.

+  (setq package-archives nil)

+# The `splicedPackages' package set, and its use by `callPackage`
+#
+# The `buildPackages` pkg set is a new concept, and the vast majority package
+# expression (the other *.nix files) are not designed with it in mind. This
+# presents us with a problem with how to get the right version (build-time vs
+# run-time) of a package to a consumer that isn't used to thinking so cleverly.
+#
+# The solution is to splice the package sets together as we do below, so every
+# `callPackage`d expression in fact gets both versions. Each# derivation (and
+# each derivation's outputs) consists of the run-time version, augmented with a
+# `nativeDrv` field for the build-time version, and `crossDrv` field for the
+# run-time version.
+#
+# We could have used any names we want for the disambiguated versions, but
+# `crossDrv` and `nativeDrv` were somewhat similarly used for the old
+# cross-compiling infrastructure. The names are mostly invisible as
+# `mkDerivation` knows how to pull out the right ones for `buildDepends` and
+# friends, but a few packages use them directly, so it seemed efficient (to
+# @Ericson2314) to reuse those names, at least initially, to minimize breakage.
+#
+# For performance reasons, rather than uniformally splice in all cases, we only
+# do so when `pkgs` and `buildPackages` are distinct. The `actuallySplice`
+# parameter there the boolean value of that equality check.
