I noticed that CentOS usually does not copy the EOL-announcement RHSA or provide the updated package associated with it.
This would be CESA-2011:0219 with upstream details at https://rhn.redhat.com/errata/RHSA-2011-0219.html
As everbody seemed to be concerned about the communication done for CentOS 3 End of Life I guess it is probably a good idea to: - duplicate the EOL-Notice RHSA as a CESA - rebuild centos-release to contain an EOL-notice - discuss wether or not to add an EOL-notice to /etc/issue
