  1) attempts in nfs-client to notify two handlers at once (this didn't work)
  2) attempts to mount a file system twice (I don't know why we included this in the first place, mounts should work first time)
  3) checks using mountpoint -q (this a) didn't work when updating a mount b) only checked the first mount)

fix up the NFS related tasks, so that the server definitly restarts after the exports are written and the mounting of filesystems on clients is correct

This reverts commit 2eb17b20.
