#
# DESCRIPTION:
# Invoke "zfs mount <filesystem>" with a filesystem whose mountpoint property
# is 'legacy' or 'none',
# it will fail with a return code of 1 and issue an error message.
#
# STRATEGY:
# 1. Make sure that the ZFS filesystem is unmounted.
# 2. Mount the filesystem using the various combinations
#	- zfs set mountpoint=legacy <filesystem>
#	- zfs set mountpoint=none <filesystem>
# 3. Verify that mount failed with return code of 1.
