Title:
  cron @reboot rules fail for users wuth autofs homes, due to missing
  upstart dependancy

Status in cron package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: cron

  If a user has a @reboot cron entry like:
  ===
  @reboot date >> date.log
  ===

  And their home directory is mounted by autofs into /home

  then, the job will fail during a machine reboot because the
  cron service starts before autofs service.

  I think this is a missing dependency between in the cron upstart
  configuration, to fix this I think that cron should be started after
  autofs (only when autofs is enabled).

  cron has a lower pid so it started first...
