How would the path become unavailable?  While it looks like a raw path,
it's still being managed by powerpath.  So during a boot, it should not
suddenly disappear, even if the path goes away. 

If it were to go away between boots, then I see it as the same situation
for a disk being renumbered/repathed on "normal" single-pathed storage.
ZFS needs to be able to scan all paths until it finds the disk again.
The pool should not be tied to the path.
