I use a VM set up this way with the following crontab:
# check for yum updates every 12 hours
5 0,12 * * * root /usr/bin/yum -q check-update 2>/dev/null
so I get an email whenever there's any updates due. I can then
evaluate, test, and (perhaps) schedule a time to manually update the
production servers.
