Today's contribution, after hardly any work (allowing for overnight
locatedb updates and anything else the cron might do.

Similar trace back.

I find it interesting that the locatedb is often supposedly corrupt at
the same time:

% locate cron
locate: `/var/lib/mlocate/mlocate.db' does not seem to be a mlocate database

After a reboot and a file system check, however, it's fine.
