The 'lame duck' may have the potential of a self-contained
re-mastering capability.

It doesn't need external storage nor another OS to complete
the re-mastering. After the kn-recombine rsync phase,
dismount the 'duck and reboot IT with the option 'noimage'
and proceed with the kn-recombine write operation.

This may require a slight tweak of kn-recombine to allow this,
but it should work since none of the files being re-arranged
are in use on a noimage reboot.
