  36 # DESCRIPTION:
  37 #
  38 # the zfs rootpool/rootfs can not be destroyed
  39 #
  40 # STRATEGY:
  41 # 1) check if the current system is installed as zfs root
  42 # 2) get the rootpool
  43 # 3) try to destroy the rootpool, which should fail
  44 # 4) try to destroy the rootpool filesystem, which should fail
  45 #
