I have read a couple old threads here on updates for servers, and I am looking for some mechanics to getting the actual updates done. I don't want automatic updates; I want to control when and what gets updated.

First I have to determine that a particular server needs updates. I suppose a daily script that would run "yum check-updates' and emails me the results could work, but then I would only want the email IF there was something to update, at my limited use of this option does not show anything to trigger a notify on changes. Does anyone know of a script that would do this?

In crontab:

MAILTO=whomever@whatever MAILFROM=this_system@whatever JOBNAME="Check for updates and report if found" ; /usr/bin/yum check-update -q

The -q suppresses output unless there is something to report. Cron handles the rest.
