You can possibly try deploying /boot/boot0 MBR selector code over disks of data pool.

The question is: why does it want to boot from raid-z at all, and how could it be persuaded to use the mirrored pool instead? Actuall I think that code on that stages just tries to boot from the pool on the current disk. -- Sphinx of black quartz judge my vow.
