# DESCRIPTION:
# 'zfs create <filesystem>' fails with bad <filesystem> arguments, including:
#	*Invalid character against the ZFS namespace
#	*Incomplete component
#	*Too many arguments
#	*Filesystem already exists
#	*Beyond maximal name length.
#	*Same property set multiple times via '-o property=value'
#	*Volume's property set on filesystem
#
# STRATEGY:
# 1. Create an array of <filesystem> arguments
# 2. Execute 'zfs create <filesystem>' with each argument
# 3. Verify an error is returned.
