Booting from ZFS would require some new code from -CURRENT tree (sys/cddl/boot, etc) and there is some limitations, e.g. it can't be used with RAID-Z volumes, etc. My personal suggestion is that you either use -CURRENT, or wait until a full MFC of ZFS v13, or use UFS /boot at this moment (note the fact that / can not be easily rolled back to previous state using ZFS's snapshot feature, and can not be easily switched between clones, use caution when working with the whole stuff). Note that, given that ZFS is more complicated than UFS, having it as / would make it harder when you got some problems and boot with LiveFS disc (the bright side is that, if you have mirrored volume as the boot volume, you get a better chance to survive a disk failure).
