Updating an existing F11 is different than F11 (virgin Install|Upgrade
on top of an F10 system).

I'm trying to speed up the Test-Change-Test cycle for the F11 Install
DVD so that Anaconda gets more testing of many different systems (raid
is my need).

A LAN connected repo sounds like a good idea for folks with an extra
system and an Anaconda smart enough to use it. A slim DVD with only
Anaconda and necessary boot time utilities - then reach out to LAN repo
for the rest.

However, for those testers in the F11 DVD test-change-test loop with
one system, jidgo DVD image creation with a recent DVD in the drive is
a quick way to create a new install DVD image. And it is possible now.
