If nothing else, yum in 6.x has history of what was updated, and if I 
remember correctly you can reinstall those same packages. If this is 
true, you can manually or automatically order yum to reinstall those 
packages just in case. Maybe mandatory reinstall of all packages 
installed that indicate they are installed from "@cr-repo" should be in 
order.

I am not sure about 5.x. If something similar exists for 5.x (and 4.x?), 
in for of a yum plugin, centos-release-CR could depend on install of 
that plugin and use it to remember all packages installed from that 
repository, so reinstall can be forced on those packages, just in case.
