I'd import the 5.6 install media. Then I'd look at the automatic repos that it creates inside of the ks_mirror directory. I'd add those as repos (you might have to sync them down then run hardlink, I'm not sure). Then add those repos to the hosts in question and do a yum update. I'm a little bit surprised that CentOS doesn't have an updates repo that you can just subscribe your systems to get these updates automatically? Unfortunately, my experience is using RHEL, so I'm just able to yum update my systems to the latest U release. I'd be interested to hear how others using CentOS are handling this issue. I'm sure it comes up quite a bit. -- Scott Henson Red Hat CIS Operator WVU Alum BSAE/BSME
