  37 # DESCRIPTION:
  38 # Once a pool has been exported, it should be recreated after a
  39 # successful import, all the sub-filesystems within it should all be restored,
  40 # include mount & share status. Verify that is true.
  41 #
  42 # STRATEGY:
  43 #       1. Create the test pool and hierarchical filesystems.
  44 #       2. Export the test pool, or destroy the test pool,
  45 #               depend on testing import [-Df].
  46 #       3. Import it using the various combinations.
  47 #               - Regular import
  48 #               - Alternate Root Specified
  49 #       4. Verify the mount & share status is restored.
