# DESCRIPTION:
#	Verify FSType-specific option works well with legacy mount.
#
# STRATEGY:
#	1. Set up FSType-specific options and expected keywords array.
#	2. Create a test ZFS file system and set mountpoint=legacy.
#	3. Mount ZFS test filesystem with specific options.
#	4. Verify the filesystem was mounted with specific option.
#	5. Loop check all the options.
