#
# DESCRIPTION:
# Once a pool has been exported, it should be recreated after a
# successful import. Verify that is true.
#
# STRATEGY:
#   1. Populate the default test directory and unmount it.
#   2. Export the default test pool.
#   3. Import it using the various combinations.
#       - Regular import
#       - Alternate Root Specified
#      Try to import it by name or guid randomly.
#   4. Verify it shows up under 'zpool list'.
#   5. Verify it can be mounted again and contains a file.
#
