How can I restore root file system in ULTRIX-32/32m?

I don't have access to an MV to try this, but I have had the same
problem with other flavors of UNIX. One solution which frequently works
is to dump the root with cpio, which will not overwrite existing files
if they are newer than the one on the tape. You can boot the mini
system and then pull everything else in, assuming that there IS cpio on
the mini system.
