In System V Release 3.0 and onwards, the option "-mount" has been
added pretty much for this reason.  (More specifically for little
machines such as a 3b2 for backing up to cartridge tape, which uses a
modified version of cpio that knows how to stream the tape.)  When the
"-mount" option is specified find will not cross over mount points.
