	I don't know about alpha (haven't had mine up and running for awhile)
but I ran into some serious lossage accessing msdos filesystems when running
the comdex snapshot.  I believe that's around 1.4.1+.  (ended up completely
trashing the filesystem)  However, I've been using msdosfs with -current
without any problems.

	Do you get this problem on any msdos filesystem?  i.e. if you
newfs_msdos a floppy can you reproduce it?  info point: 1.4S doesn't
seem to have this problem for me.
