This morning I applied the recent updates to CentOS-5.6 on a test and development host and observed this:

Oh, and I would point out that if you did not have at least one kernel installed that is above the 2.6.18-203.el5 version, then the package would not install at all, so in this case you likely have a mix of older and newer kernels on the box.
We keep the last three kernels installed as a matter of policy and the oldest of these on the development box is kernel-2.6.18-194.32.1.el5. I do not plan on booting into an older kernel on this host. Therefore, I will work from the assumption that this issue is not going to cause us any difficulty and will disappear on its own with the next kernel update.
Thank you.
