Feel surprised to find in the RHEL 5.3 release notes the following
While anaconda's "upgrade" option will perform an upgrade from
Red Hat Enterprise Linux 4.7 or 5.2 to Red Hat Enterprise Linux
5.3, there is no guarantee that the upgrade will preserve all
of a system's settings, services, and custom configurations.
For this reason, Red Hat recommends that you perform a fresh
installation rather than an upgrade.
So they are advising to reinstall RHEL 5.3 even when you're running RHEL
5.2. Which seems scary to me. I would hope this is mostly because of the
many Xen improvements and thus mostly for their Advanced Platform.
But still, this is certainly no good evolution.
