#
# DESCRIPTION:
#   Verify 'zfs destroy -f' succeeds as root.
#
# STRATEGY:
#   1. Create filesystem in the storage pool
#   2. Set mountpoint for the filesystem and make it busy
#   3. Verify that 'zfs destroy' fails to destroy the filesystem
#   4. Verify 'zfs destroy -f' succeeds to destroy the filesystem.
