40#
41# DESCRIPTION:
42#	Invoke "zfs mount <filesystem>" with a filesystem
43#	which mountpoint be the identical or the top of an existing one,
44#	it will fail with a return code of 1
45#
46# STRATEGY:
47#	1. Prepare an existing mounted filesystem.
48#	2. Setup a new filesystem and make sure that it is unmounted.
49#       3. Mount the new filesystem using the various combinations
50#		- zfs set mountpoint=<identical path> <filesystem>
51#		- zfs set mountpoint=<top path> <filesystem>
52#       4. Verify that mount failed with return code of 1.
53#
54# TESTABILITY: explicit
55#
56# TEST_AUTOMATION_LEVEL: automated
57#
58# CODING_STATUS: COMPLETED (2005-07-11)
