Comment 1 for bug 159516

Note there is a bug in the findutils update in gutsy which causes it to either not run properly ionice'd or not run at all:
  https://bugs.edge.launchpad.net/ubuntu/+source/findutils/+bug/152692

But it also will ionice process 7, whatever that is, if it exists :-(

On a fresh gutsy install I have both findutils and slocate, and see 2 of those jobs, but don't see /etc/cron.daily/find.notslocate.dpkg-new
