Hmm... guess I didn't realize there was a difference :)
I want the OS to "run" from /dev/da0s1h so that I can then completely wipe
and replace /dev/da0s1a .

to which file?
 The box is a new 5.3 install. My thought was to boot from da0s1h,
buildworld/kernel for 6 with a DESTDIR pointing to the original /
(da0s1a). Then reboot and have a clean install of 6.
