I been using RH since about 4.1 release and then one thing that I always
do is install it to another "root" partition rather doing the upgrade. 

My setup is such that I have two root partitions that I install to. This
way, I don't ever do an upgrade. If there is a problem, I just go back to
the other root parition while I figure out what to do with the new install
and then do it or redo it. This way I don't ever touch the running root
patition until I switch over. 

I guess me working with Mainframe disk volumes kinda steered me this way.
In the IBM mainframe world, when one does an ipl(boot), it's from a disk
volume. A disk volume is kinda like a disk partition in the PC world. Of
course, in the PC world, the boot is done from the first disk drive or a
floopy drive or from a CD drive or even a tape drive but it's the same
principle.
