Of course I am.

It shouldn't be too terribly difficult, although the hard part is
testing it and making sure it all works :-)  anaconda-devel-list has a
couple of posts from me describing how to use an updates.img for easier
testing (basic summary: make an ext2 image, drop it as Fedora/base/
updates.img, mount via loopback, copy updated python files there).

The basic idea of what needs changing is to look at the RAID stuff in
fsset.py and convert it over from using the various raid-tools commands
to using mdadm based ones.  Also, there might be some changes needed in
raid.py, but I doubt it (since raid.py mostly just works with the
underlying ioctls)
