# mdconfig -f /home/zfstest -u 0
mdconfig: ioctl(/dev/mdctl): Device busy

I already got couple of memory disks, so I choose available md.

# mdconfig -f /home/zfstest -u 2
# bsdlabel -w md2 auto
# zpool create home /dev/md2c
default mountpoint '/home' exists and is not empty
use '-m' option to provide a different default
# zpool create zfs /dev/md2c
# mount
/dev/ad0s2a on / (ufs, local, soft-updates)
devfs on /dev (devfs, local)
/dev/ad0s2e on /var (ufs, local, soft-updates)
/dev/ad0s2f on /usr (ufs, local, noatime, soft-updates)
procfs on /proc (procfs, local)
linprocfs on /usr/compat/linux/proc (linprocfs, local)
/dev/md1 on /tmp (ufs, local)
zfs on /zfs (zfs, local)

Wrote couple of files into /zfs, then tried to delete them- computer rebooted. 
This was remote box and I am unable to see any information what happened- log 
files shows nothing.
