#
# DESCRIPTION:
# An exported pool can be imported under a different name. Hence
# we test that a previously exported pool can be renamed.
#
# STRATEGY:
#   1. Copy a file into the default test directory.
#   2. Umount the default directory.
#   3. Export the pool.
#   4. Import the pool using the name ${TESTPOOL}-new,
#      and using the various combinations.
#               - Regular import
#               - Alternate Root Specified
#   5. Verify it exists in the 'zpool list' output.
#   6. Verify the default file system is mounted and that the file
#      from step (1) is present.
