anaconda doesn't have any support for multipath, so to do an upgrade, you have
to get down to a single path situation.

I've already deduced that. Turning back to a single path situation is not a nice
task in a complex environment like a blade center conected to a Fibre Channel
fabric, and it would be nicer to your paying customers, and probably easier, to
get multipath into the installer kernel and some intelligence, rather than
forcing your customers to downgrade a perfectly functional system.
