#
# DESCRIPTION:
#	Try each 'zpool checkpoint' and relevant 'zpool import' with
#	invalid inputs to ensure it returns an error. That includes:
#		* A non-existent pool name or no pool name at all is supplied
#		* Pool supplied for discarding or rewinding but the pool
#		  does not have a checkpoint
#		* A dataset or a file/directory are supplied instead of a pool
#
# STRATEGY:
#	1. Create an array of parameters for the different scenarios
#	2. For each parameter, execute the scenarios sub-command
#	3. Verify that an error was returned
#

# Scenario 2
# If the pool does not have a checkpoint, -d nor import rewind
# should work with it.
