# ID: zpool_import_012_pos
#
# 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. 
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2006-11-01)
