#
# DESCRIPTION:
#	Try each 'zfs unmount' with inapplicable scenarios to make sure
#	it returns an error. include:
#		* Multiple filesystem|mountpoint specified
#		* '-a', but also with a specific filesystem|mountpoint.
#
# STRATEGY:
#	1. Create an array of parameters
#	2. For each parameter in the array, execute the sub-command
#	3. Verify an error is returned.
