  Log Message:
  -----------
  conf: error out on too many mappings

The kernel only allows 4k writes to most files in /proc including {g,u}id_map
so let's not try to write partial mappings. (This will obviously become a lot
more relevant when my patch to extend the idmap limit in the kernel is merged.)
