I don't understand this part. You can certainly do 5.0 -> 5.1 style upgrades "in-place", and you can upgrade between major versions using boot media (either net boot, CD, whatever) if you wish, no requirement to format the drive. We literally have systems that were running 2.1 that have been upgraded through 3 -> 4 -> 5, currently on 5.4. Certainly you have to do some manual cleanup between major versions, updating configs, etc, but it's pretty easy stuff. I just recently did a 3 -> 4 -> 5 cycle on a system in about three hours, and it was an old 700Mhz system at a remote site and a lot of the time was waiting for the 5.4 updates to download over their T1. While the updates were downloading I worked on cleaning up the config files, removing old/obsolete packages, etc. Afterwards I had a nice, clean RHEL5.4 system, with SElinux and it's run fine ever since.
