In FC5, every night, I get an email (to root), with subject: Subject: Updates available for <machine name> === === yum reports available updates: === ... Looks like output from "yum check-update" I need to disable that - don't really need to know every day what is new, how do I disable this? There is certainly no check-update job in /etc/cron.daily (there is a yum.cron there, but that is for automatically applying updates, and the default is off, so that job is certainly not running).
