 Ok, kernel version 8.99
 
 gpt create wd0
 gpt add -s 2g -t fbsd-zfs -l zfs-bsd wd0
 dkctl wd0 listwedges
  > zpool create pool dk0
 internal error: Inappropriate ioctl for device
  >zpool create pool wd0a
 cannot create: 'pool' : one or more vdevs refer to the same device
 
 Ok, I guess its handled in 8.99 -- though the messages are a bit cryptic.
 
 Note:
 
 gpt destroy wd0Â Â Â Â Â Â Â Â Â Â Â Â Â  # wipes the partition table but dkctl does 
 not know about this
 dkctl wd0 delwedge dk0 # to clean up.
 
 Notes: OpenIndiana hipster allows zfs in mbr partition, and recommends 
 gpt with whole disk only
 
 zpool does succeed with wd0 (wd0a same error as a above it mbr or gpt 
 (whole disk));
 but disk label tools fdisk and gpt can not report what file system is 
 using the disk
 
 Conclusions:
 I don't understand what is the point of dk* devices.
 It seems that zfs can not be used: to install into, nor on the same disk 
 as an ffs root
 What is the point of /dev/zpool/ ?
 The problem seems to be resolved in zpool application for netBSD image 8.99
