Since I'm trying to install specific versions of packages with Puppet, this is a problem.  The most recent one that just turned up this morning is kernel-devel.  I have the following resource defined in one of my Puppet manifests:

I naively assumed that once a package was made available via the official CentOS mirrors that it would never disappear.  That doesn't appear to be the case.  I have  kernel-2.6.32-279.19.1.el6.x86_64 installed. kernel-devel-2.6.32-279.19.1.el6.x86_64 is gone, apparently replaced with kernel-devel-2.6.32-358.0.1.el6.x86_64. I have a couple of other packages that have given me problems, too, namely ngircd which was upgraded from 18 to 20.1.

CentOS only releases the LATEST trees when do a point release.  (That is
moving from CentOS-6.3 to 6.4)

Our main version is 6 and that will always point to the latest point
release.  Last week that was pointing to 6.3, now it is pointing to 6.4.

If you do not want to upgrade to the lastest CentOS version, then you
have to create your own mirrors and do your own version control.

You can also get any previous version of centos from the centos vault:

http://vault.centos.org/

So, if you go to the 6.3 tree, you can get that older kernel-devel package.

NOTE:  that kernel has security issues and has been replaced.
