Hmm, would be usable but I think of two things:
1. It would be cute to have a script line mkkickstart which generates the
config for an Upgrade (easy i think)
2. One might have to make sure if there is enough disk-space for the
upgrade, before you launch it. (but how?)

and these are availiable more oten than NFS (firewalls, ...)
