The boot block currently lives in blocks outside of the filesystem.
Thus, mirroring does not, in itself, replicate this boot
information.> For example:

This is true. ZFS boot will be coming at a future date.

To be clear: No, ZFS mirroring does not currently mirror the boot
block. Yes, all necessary boot information will be mirrored when ZFS
becomes bootable.
I hope that this helps. Please let me know if you need more information.
