Eelco Dolstra 6f03065dce * Move the setting of $MODULE_DIR to modprobe.nix.
* Add a slash to the end of $MODULE_DIR, as expected by depmod.  (Not
  that running depmod from the command line is all that useful, since
  you can't use it to update the tree in the Nix store.  But at least
  commands like "depmod -n" work now.)  Reported by Kirill Elagin on
  IRC.
