Yeah.  I tried this entire procedure and encountered the same partial
sucess you have had.  In my case I was booting a SPARC IPC from my NetBSD
1.1B equiped uVAX-II.  Got as far as mounting swap and blamo.  I had the
same problems with trying to guess how the heck to export a "file."  I
got all the same sorts of errors you did.  Since I am a pinhead, I don't
know how to do this and thankfully got some good advice and instead built
a terrific little portable SCSI drive I then used to bootstrap SPARC boxes
from scratch.  Not exactly as easy with a VS2000 though I don't think.
Thought I'd add my usual whiny two-bits given I was doing the inverse,
booting a non-VAX box from a VAX via the documented "diskless" method...
