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. svn path=/nixos/branches/modular-nixos/; revision=16350
