The merge proposal has been confirmed and verified on lucid.

** Description changed:
  Binary package hint: autofs5
+ 
+ [Impact]
+ Running reload autofs on a release with this issue creates automount maps and 
can cause the automounter to hang. This will prevent logins via ssh for users 
(due to NFS mounted home directories).
  
  I have an automount setup containing a large number of NIS-provided
  maps, all derived from an NIS-provided master map (yp:auto.master). When
  I stop automount using "stop autofs", I noticed that some mounts have
  been unmounted while a non-deterministic number of mounts have been
  orphaned and need to be cleaned up using "umount":

  auto.exit26home /exit26 autofs 
rw,relatime,fd=55,pgrp=13244,timeout=60,minproto=5,maxproto=5,indirect 0 0
  
  I suspect this is due to the transition to upstart but I'm not 100%
  sure.
