   mounted-tmp uses 'find' -- but if /usr is not yet available it will fail

  Upstart job to clean /tmp does not run when /usr is on a seperate
  partion

  Binary package hint: mountall

  Hi!

  I discovered this problem when an improper shut down of the server
  before all clients had shutdown on an LTSP system. It seems that the
  client when it logs out deletes files in /tmp that confuse it when
  booting again(that is another bug report). However, this can cause
  problems with /tmp filling up the hard drive with unneeded files that
  should otherwise be deleted on boot.

  Ubuntu forum user tall-male also discovered this. See his post here:

  http://ubuntuforums.org/showthread.php?p=9558012#post9558012

  Here is a summary and fix:

  The automatic cleanup of /tmp at boot time is not working. It wasn't
  working in Ubuntu 9.10, neither in the new 10.04.

  The problem seems to happen using a separate /usr partition.

  According to /etc/init/mounted-tmp.conf, cleaning starts when /tmp is mounted:
  start on mounted MOUNTPOINT=/tmp
  However, the script needs /usr/bin/find to cleanup /tmp. Cleanup is failing since /usr is not there (is not mounted) when cleaning starts. Therefor, /tmp is never cleaned

  Changing it to:
  start on local-filesystems
  solved the problem. The cleanup is only started when all local file systems are mounted.

  I can confirm that this change does work.

  I filed this report first against upstart itself not knowing what
  package it should be filed against.
