	Missing 'dd' typo.  It's on the other system I tried copying the 8G
to a slightly large 9G partition -- that worked.  On the source system
I can copy 8G to another 8G partition.  Just running them over rsh seems to
be a problem.  Same version of 'dd' on each side (SuSE 7.2).

	Maybe I can fool ftp with symlinks tomorrow into doing the copy and see
if that works.  Just for fun I tried 'cat' as well -- same error -- out of
space on target.

It transfers a lot of data -- right around 2G the first time I tried it, so
it looked awfully suspicious.
