35#
36# DESCRIPTION:
37# Invoke "zfs mount <filesystem>" with a filesystem but its mountpoint
38# is currently in use.  Under Linux this should succeed and is the
39# expected behavior, it will fail with a return code of 1 and issue
40# an error message on other platforms.
41#
42# STRATEGY:
43# 1. Make sure that the ZFS filesystem is unmounted.
44# 2. Apply 'zfs set mountpoint=path <filesystem>'.
45# 3. Change directory to that given mountpoint.
46# 3. Invoke 'zfs mount <filesystem>'.
47# 4. Verify that mount succeeds on Linux and FreeBSD and fails for other
48#    platforms.
