#
# DESCRIPTION:
#	'zfs clone' should fail with inapplicable scenarios, including:
#		* Null arguments
#		* non-existant snapshots.
#		* invalid characters in ZFS namesapec
#		* Leading slash in the target clone name
#		* The argument contains an empty component.
#		* The pool specified in the target doesn't exist.
#		* The parent dataset of the target doesn't exist.
#		* The argument refer to a pool, not dataset.
#		* The target clone already exists.
#		* Null target clone argument.
#		* Too many arguments.
#
# STRATEGY:
#	1. Create an array of parameters
#	2. For each parameter in the array, execute the sub-command
#	3. Verify an error is returned.
