Two small points: 1) I noticed that the yum update had not run on a recenly installed 4.4 machine. Turned out that /var/lock/subsys/yum did not exist - don't know why, has anyone else had this experience on 4.4? 2) I also spotted a small error in /etc/cron.daily/yum.cron if [ utime -ge 72000] should be if [ $utime -ge 72000 ] Alex Finch
