If this is a zfs-on-root install you may have problems with importing the zpool and getting access to your data. I would advice you import the zpool with the -N option -N Import the pool without mounting any file systems. This will prevent it from automatically mounting filesytems on top of the LiveCD OS you're booted into and causing major problems. After you've done this, change your /boot filesystem to somewhere new/accessbile that won't conflict with the running OS and copy in the kernel. The process will look something like this: zpool import -N tank zfs set mountpoint=/newboot /tank/boot zfs mount /tank/boot mv /newboot/kernel /newboot/kernel.old cp -R /boot/kernel /tank/boot/ zfs umount /tank/boot zfs set mountpoint=/boot tank/boot gpart bootcode -b /boot/pmbr -p /boot/gptboot -i 1 ada0 reboot Good luck!
