#
# DESCRIPTION:
# Verify that an exported pool cannot be imported
# more than once.
#
# 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
#   4. Verify it shows up under 'zpool list'.
#   5. Verify it contains a file.
#   6. Attempt to import it for a second time. Verify this fails.
#
