This probably needs key change for pools to work to be functional..nevertheless
it's a test case..
After fixing 943 (zfs key -c, out of memory) and fixing a problem where
changing the keysource still asked for key data, i got a panic on the below...
tank/enc keysource passphrase,prompt local
tank/enc keyscope dataset local
bash-3.2# zfs key -c -o keyscope=pool tank/enc
salt= 0
keydata=
keysource=
dataset name=tank/enc

This then causes a really bad scenario where you can't boot the machine and
even after doing a 'zpool destroy tank' in single user mode, it still panics..
I'm now having to reinstall the BE.. :)
