ZFS: can't read MOS of zpool...

["Alexandre C. Guimarães"]

Hello,

I don't get those messages when booting from the installation media, all
disks are apparently showing up correctly from `gpart list` from there, and
I updated the bootblocks:

---
# gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada0
---

however the error messages still do persist on the installed system.

Do I forgot and am not aware of anything?

Thank you.
