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