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#

55# but some filesystems can become unmounted in the process, and aren't
56# automatically remounted.
