Title:
  unmounted-remote-filesystems event deadlocks nfs-root

Status in “sysvinit” package in Ubuntu:
  Triaged

Bug description:
  From the changelog:

  sysvinit (2.87dsf-4ubuntu17.5) lucid-proposed; urgency=low

    * debian/initscripts/etc/init.d/umountnfs.sh: emit a new event,
      unmounted-remote-filesystems, to allow stopping portmap
      and others. (LP: #711425)

  Updating from this package makes the system hang on shutdown:

   * All processes ended within 1 seconds....                              [ OK ] 
  init: Connection from private client
  init: Handling unmounted-remote-filesystems event
  init: portmap goal changed from start to stop
  init: portmap state changed from running to pre-stop
  init: portmap pre-stop process (2672)
  init: portmap pre-stop process (2672) exited normally
  init: portmap state changed from pre-stop to stopping
  init: Handling stopping event
  init: statd goal changed from start to stop
  init: statd state changed from running to pre-stop
  init: statd state changed from pre-stop to stopping
  init: Handling stopping event
  init: statd state changed from stopping to killed
  init: Sending TERM signal to statd main process (856)

  The system is using nfsroot so / is mounted as NFS and remains
  mounted. In that case I think it is wrong to emit the umounted-remote-
  filesystem event.
