nixpkgs/test/rescue-system.nix
Eelco Dolstra a94dd5c8b1 * Given a kernel build (with modules in $kernel/lib/modules/VERSION),
`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.
