Once per day cron will run every script in /etc/cron.daily, which includes yum.cron. That script first checks to see if yum was enabled by /etc/init.d/yum; to do this it checks for the existence of /var/lock/sybsys/yum. If that file is not present the script just exits without doing anything. Otherwise it invokes yum. This arrangement allows you to use the standard initscripts system (chkconfig, service, and various graphical tools) to control whether or not yum runs nightly. Otherwise you'd have to manage things manually. Of course, you still can do things manually if you really want to. - J<
