	Might I suggest that you use cpio on a neewe system to extract
it to a fixed directory, and then use cpio again to make a new cpio
archive of that directory, so you can use it to extract on the
MightyFrame.

	Beware of default options -- unless everything is using the "-c"
(character mode) for all the parameters, so you don't have to worry
about swapping bytes or words in the extraction.

	Note that the cpio on Solaris 10 uses -R to change ownership of
the files and directories.

 ======================================================================
     -R id         Reassigns ownership and group information  for
                   each  file  to  user  ID.  (ID must be a valid
                   login ID from  /etc/passwd.)  This  option  is
                   valid only for the super-user.
 ======================================================================

	An alternative might be to set up a chroot partition, so the OS
*thinks* (as far as cpio is concerned) that everything belongs below the
current directory, and it can't even *see* the normal root tree.  A bit
tricky to set up, but it should do what you want.

	Good Luck,
