 Setting "off" disables disk filesystem manipulations. This is the default
 unless the program was started with leafname "osirrox". Elsewise
 the capability to restore files can be enabled explicitly by -osirrox "on".
+It can be irrevocably disabled by -osirrox "banned".

 To enable restoring of special files by "device_files" is potentially
 dangerous.
