# DESCRIPTION:
# Setting valid mountpoint to filesystem, it is successful.
# Whatever is set to volume, it is failed.
# 'zfs set mountpoint=<path>|legacy|none <fs|ctr|vol>'
#
# STRATEGY:
# 1. Setup a pool and create fs, ctr within it.
# 2. Loop all the valid mountpoint value.
# 3. Check the return value.
