for a separate tree.
* Pass the path of the modules tree to modules so that you don't have
to write absolute paths, e.g. you can say
require = [ "${modulesPath}/hardware/network/intel-3945abg.nix" ];
instead of
require = [ /etc/nixos/nixos/hardware/network/intel-3945abg.nix ];
The latter is bad because it makes it hard to build from a different
NixOS source tree.
