Description of problem: Current %post is: /sbin/chkconfig --level 2345 anacron resetpriorities this results in: [root@vault ~]# /sbin/chkconfig --del anacron [root@vault ~]# /sbin/chkconfig --level 2345 anacron resetpriorities [root@vault ~]# chkconfig --list anacron anacron 0:off 1:off 2:off 3:off 4:off 5:off 6:off on a fresh install. I think you need to distinguish between fresh installs and upgrades and use chkconfig --add on installs.
I didn't test whether fresh install works ;-) now it's okay.
