Are you sure about this? the public repo seems to show 2.6.18/2.6.32.. This would actually be a dis-advantage in many cases, as a number of vendor utils (I'm looking at you HP) don't play nice w/ 3.x kernels.

They have the Unbreakable Enterprise Kernel (UEK), as well as a RHEL-compatible kernel. I'm not sure which is the default in new installs.

From the release notes: "By default, both the Unbreakable Enterprise Kernel and the Red Hat Compatible Kernel are installed on the x86_64 (64 bit) platform, and the system boots the Unbreakable Enterprise Kernel by default. If needed, /etc/grub.conf can be modifed to make the system boot with the Red Hat Compatible Kernel by default."

So for the avoidance of doubt, the CentOS upgrade script will preserve the RHEL/CentOS 2.6.32.x kernel, but a fresh install from the netboot or dvd will install the UEK 3.0 install?

Correct.
