Yeah, the reason we have the yum upgrade instructions page is that it's
simply not always possible to ensure a straightforward 'switch repos and
yum upgrade' (or, better, 'yum --releasever=XX distro-sync') will
completely work. That's also why yum isn't an officially supported
upgrade method. /usr move is a good example, really. It would be
impossible, really, to handle it through RPM scripts/triggers alone.
