This sequence is working for me:
dd if=/boot/zfsboot of=/dev/da0 count=1
dd if=/boot/zfsboot of=/dev/da0 skip=1 seek=1024
zpool create zroot /dev/da0
zpool set bootfs=zroot zroot
cd /usr/src && make installworld installkernel distribution DESTDIR=/
zroot
cp /boot/loader.conf /zroot/boot/loader.conf
cp /etc/rc.conf /zroot/etc/
touch /zroot/etc/fstab
echo 'zfs_load="YES"' >>/zroot/boot/loader.conf
echo 'vfs.root.mountfrom="zfs:zroot"' >>/zroot/boot/loader.conf
zpool export zroot
zpool import zroot
cp /boot/zfs/zpool.cache /zroot/boot/zfs/
zfs set mountpoint=legacy zroot
... except that it doesn't anymore. I saw this working about two
months ago, but now it fails to mount root. Verbose boot doesn't give
any indication why ZFS can't find the pool.
