I happen to agree with Adam McDougall and prefer:

	p1=boot, p2=swap, p3=zpool

The reason is simple... we're progressing to a point where we support live
resizing. If you put the swap after the zpool, you have to (as you accurately
stated) remove the swap and then re-add it. Problem is for a live resize, you
don't necessarily want to remove all your swap simply to grow your filesystem.

Having the zroot pool always built upon devices residing at the EOD will
mean that we can better support live-resizing without shuffling.
