I followed the link in the first post, followed the instructions, and I'm happy to report, everything worked well enough. It took about three hours to complete the upgrade. There were a few packages I had to make selections for, from a list. Other than the consumed time, this was a very easy way to upgrade one level; 2008 to 2008.1.
Grub was updated with the "Spring" boot option. Fstab was not disturbed. So the basics are all there. I will do some more testing, and report what I find.

It has taken some time to sort out all the minor problems.
The biggest one was the proprietary nvidia driver was installed, but would not install. I don't know why, what I did to get it going, was uninstall with urpmi, and then re-install. I could then get the nvidia driver to load and run. Compiz won't start, you can't enable it with out the nvidia driver. I had to use XFdrake, select the card, quit, and follow the prompt to install the nvidia driver. All is good with Compiz, and Nvidia now.
All my servers are running, and didn't require any tweaking. That includes Cups, Samba, NFS and SSH. This was the biggest benefit of installing from the repos.

A clean install takes me several days of configuring to get things back to normal.
Hope this helps anyone considering an upgrade from the repos...
