   On Linux platforms, Thunar requires HAL 0.5 or better to provide information
   about volumes.
 
-  To be able to mount and unmount volumes, you will also need either the pmount
-  utility or HAL with fstab-sync. Thunar may also support gnome-mount in the
-  future.

   To be able to eject dics, you will need the eject utility program.
