Typically the way this works is to copy the root image off of tape into the
future swap partition. Then perform a special boot that does all processing in
real memory, no use of the swap space. This "mini-unix" (munix in Sun terms)
is used to setup the other filesystems copying the OS files from the rest of
the tape or other tapes. Then you boot the newly constructed system.
I have never heard of actually running the OS off of tape, though it can be
done with CD-ROM using the same type of swap less execution.
