FreeBSD ZFS on root. Access zroot from a live CD

<-----69------------------------------------------------------------>

I managed to access my zroot partition from a live CD by Following
the steps below.

Boot into Live CD

run zpool import to get name of zpool (probably zroot)
# zpool import

create a mountpoint for zpool:
# mkdir -p /tmp/zroot

import zpool:
# zpool import -fR /tmp/zroot zroot

create a mountpoint for zfs /:
# mkdir /tmp/root

mount /:
# mount -t zfs zroot/ROOT/default /tmp/root

the directories will now be available in /tmp/root
make changes or save your stuff as needed

export zpool:
# zpool export zroot

boot normally
