35#
36# DESCRIPTION:
37#	Invoke "zfs mount <filesystem>" with a filesystem
38#	which mountpoint be the identical or the top of an existing one,
39#	it will fail with a return code of 1
40#
41# STRATEGY:
42#	1. Prepare an existing mounted filesystem.
43#	2. Setup a new filesystem and make sure that it is unmounted.
44#       3. Mount the new filesystem using the various combinations
45#		- zfs set mountpoint=<identical path> <filesystem>
46#		- zfs set mountpoint=<top path> <filesystem>
47#       4. Verify that mount failed with return code of 1.
48#
49# TESTABILITY: explicit
50#
51# TEST_AUTOMATION_LEVEL: automated
52#
53# CODING_STATUS: COMPLETED (2005-07-11)
