Quite; Mac OS X has already introduced a little confusion with the
difference in its zpool versions:
galoot% uname -a
SunOS galoot 5.11 snv_85 i86pc i386 i86pc
galoot% /usr/sbin/zpool upgrade -v |grep 6
6 bootfs pool property
crackityjones:~ ceri$ uname -a
Darwin crackityjones.private.submonkey.net 9.2.2 Darwin Kernel Version 9.2.2:
Tue Mar 4 21:17:34 PST 2008; root:xnu-1228.4.31~1/RELEASE_I386 i386
crackityjones:~ ceri$ zpool upgrade -v |grep 6
This system is currently running ZFS version 6.
6 bootfs pool property and OSX directory type
I've yet to check what happens with a zpool created on the Mac being
imported on the OpenSolaris machine or vice versa.

That must be wonderful! I don't understand it at all.
