This is one of those rare uses for the CHROOT command.  The steps are:

	chroot /sparedir cpio...

I'd read the manual very carefully, and try it with something not too
destructive.  Once done, the files will have been retrieved RELATIVE TO
/sparedir AS THOUGH IT WERE THE ROOT.  You can then move them or whatever
you want to do with them.
