How funny! I did not even know that fstype in the disklabel can be "ZFS". I
have only seen "swap" and "4.2BSD" so far.

$ gpart add -t freebsd-zfs md0s1 && disklabel md0s1
md0s1a added
# /dev/md0s1:
8 partitions:
#          size     offset    fstype   [fsize bsize bps/cpg]
  a:       4095          0       ZFS
  c:       4095          0    unused        0     0     # "raw" part, don't edit
$

Do you know how to create a beadm-friendly zroot manually (like the one
created automatically by bsdinstall)?
