#
# DESCRIPTION:
# Once a pool has been exported, it should be recreated after a
# successful import, all the sub-filesystems within it should all be restored,
# include mount & share status. Verify that is true.
#
# STRATEGY:
#   1. Create the test pool and hierarchical filesystems.
#   2. Export the test pool, or destroy the test pool,
#       depend on testing import [-Df].
#   3. Import it using the various combinations.
#       - Regular import
#       - Alternate Root Specified
#   4. Verify the mount & share status is restored.
