#
# 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.
#
