`modules-closure.nix' produces a module tree in $out/lib/modules/VERSION that contains only the modules identified by `rootModules', plus their dependencies. It also generates an appropriate modules.dep. This is useful for initrds, as we obviously don't want a copy of the entire kernel module tree in the initial RAM disk. svn path=/nixu/trunk/; revision=6939
