  35 # DESCRIPTION:
  36 #
  37 # the zfs rootpool can not be destroyed
  38 #
  39 # STRATEGY:
  40 # 1) check if the current system is installed as zfs root
  41 # 2) get the rootpool
  42 # 3) try to destroy the rootpool, which should fail.
  43 # 4) try to destroy the rootpool filesystem, which should fail.
