There is an updates.img for anaconda that potentially fixes a variety of
bugs.  It's linked to off the bugs in question, but we're still
developing fixes for a couple things and waiting to see what other
common bugs are rolling in.

In my opinion, using the updates.img in media being made for release
would be useful so we don't get another batch of bug reports about the
same things.
