Comment 16 for bug 508083

The timing of this (old) bug's appearance is very suggestive of a problem
related to the eglibc 2.15 upgrade. cron is one of the services that's
required to be restarted for eglibc upgrades due to use of NSS, and this
should already have been done automatically. I had a look at the term log,
and see this output:

Checking for services that may need to be restarted...
Checking init scripts...
WARNING: init script for samba not found.

Restarting services possibly affected by the upgrade:
  vsftpd: restarting...done.
  spamassassin: restarting...done.
  ssh: restarting...done.
  snmpd: restarting...done.
  slapd: restarting...done.
  saslauthd: restarting...done.
  rsync: restarting...done.
  mysql: restarting...done.
  dovecot: restarting...done.
  exim4: restarting...done.
  cups: restarting...done.
  cron: restarting...done.
  atd: restarting...done.
  autofs: restarting...done.
  apache2: restarting...done.

Services restarted successfully.

So cron should have been restarted as part of the upgrade, but there's an arbitrary window between libc6 unpacking and crond being restarted. Either we should stop cron from the libc6 preinst (since we know it's not going to run right), or we should somehow suppress these crash reports during the upgrade.
