The default crontab gets a lil annoying as it mails output from scripts. You get quite a few of these: rm: cannot remove `/var/spool/cron/lastrun/cron.hourly': No such file or directory Just redirect the output do /dev/null to solve this :)
ummm, no. If you are getting e-mails from cron, then that means that a cron job is failing. What you need to do is # chown -R root.cron /var/spool/cron and # chmod -R ug+rwX /var/spool/cron Then the error will go away, and cron will no longer send you e-mails.
yes - the commands from comment #1 fix the situation, but it should only be a problem if you update from a old cron (ie. before the new cron layout) ... otherwise it probably is a configuration error
