This isn't perfect. 

I've seen filesystems created on Digital UNIX 4.0 (no letter) go screwy
on NetBSD. Specifically, the root directory of the DU partition (I think
it was /usr) was (according to NetBSD) empty when it actually had lots
of files in it.

It started out OK, but as I did more stuff in DU it got worse on the
NetBSD side.
