On quick look I haven't found a place where a compatibility setting is=20= =20 used=20for the rpool during the creation, so I can't point out what the=20= =20 exact=20difference is. Given that empty_bpobj is not in the list of the boot code, it can't=20=20 be=20the same, some limit of enabled features has to be in place during=20= =20 initial=20install, and your example has to be different.
