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 ]
