I've added a new default ZFS layout which should work better with beadm.
I'm going to be doing some testing with it here soon.

That would be the ideal, plus we may need to write a GUI front-end to
it, so users can easily create a BE, and revert back anytime they want.

Does grub support this? Or does the beadm manager do some configuration
of the grub config manually? I'm not sure how long it would take to get
the FreeBSD boot-loader hacked to support this, maybe grub is something
worth looking into since Solaris is using it for this as well?

If you want to play around with getting grub working, that would be cool
:) One thing I know grub needs is support for detecting FreeBSD on root
setups, when running "grub-mkconfig". If that was setup properly, then
we could see about using it as the boot-loader.
