zfs filesystems don't show up in vfstab because they are 
mounted/unmounted/etc. through zfs(1M).

zfs filesystems do, however, show up in the output of mount(1M) and df(1M)

You can explicitly put a zfs pool anywhere you want it. Just create the 
pool thusly:

zpool create -m /whatever/path/you/want pool_name c0t0d0
