# __stc_assertion_start
#
# ID: mountpoint_002_pos
#
# DESCRIPTION:
# 	If ZFS is currently managing the file system but it is currently unmoutned, 
#	and the mountpoint property is changed, the file system remains unmounted.
#
# STRATEGY:
# 1. Setup a pool and create fs, ctr within it.
# 2. Unmount that dataset
# 2. Change the mountpoint to the valid mountpoint value.
# 3. Check the file system remains unmounted.
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2005-07-04)
