I have to say, I've never seen this. I'm sure Chris and the other CMU
folks understood this in detail -- I understand that they did patch the
OSF/1 source to deal with this ...
I think there is a subtle issue there .. the problem only occurs if you
run mknod(8) on OSF/1 ^W DU ^W Tru64, or something like that. I've been
told that if you use gtar under DU to unpack the sets, or, if you (like
me) run our tar or pax from NetBSD over an NFS-mounted drive, then the
nodes you get back will work just fine. I used NFS roots exported from DUh
servers all the time last year at Avalon. In fact, I never actually was
able to see this problem...it would be interesting to see a failure test
