Only thing I'd note here is that udevsettle can, on occassion, take
several minutes to get around to finishing.  I added a wait window in
turnOnFilesystems that explains what's going on, though most of the time
it'll display only very briefly.  On the rare occassion that udevsettle
takes a very long time, at least anaconda doesn't look hung.  You may
wish to consider that here too.
