# description: This script will mount/umount the zfs filesystems during
# system boot/shutdown. Configuration of which filesystems
# should be mounted is handled by the zfs 'mountpoint' and
# 'canmount' properties. See the zfs(8) man page for details.
# It is also responsible for all userspace zfs services.
