# ID:  zpool_set_002_neg
#
# DESCRIPTION:
#
# Malformed zpool set commands are rejected
#
# STRATEGY:
#	1. Create an array of many different malformed zfs set arguments
#	2. Run zpool set for each arg checking each will exit with status code 1
#
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2007-03-05)
