31# DESCRIPTION:
32# The following options can be set on a temporary basis using the -o option
33# without affecting the on-disk property. The original on-disk value will be
34# restored when the file system is unmounted and mounted.
35#
36#         PROPERTY		MOUNT OPTION
37#	  atime			atime/noatime
38#	  devices		devices/nodevices
39#	  exec			exec/noexec
40#	  readonly		ro/rw
41#	  setuid		setuid/nosetuid
42#
43# STRATEGY:
44#	1. Create filesystem and get origianl property value.
45#	2. Using 'zfs mount -o' to set filesystem property.
46#	3. Verify the property was set temporarily.
47#	4. Verify it will not affect the property that is stored on disk.
