Nautilus should watch or periodically check fstab to see if there are new
mount points that nautilus can mount/unmount via the desktop's right-click
context menu.

For instance:
I plugged in my camera (Minolta Dimage 7) and hotplug and/or kudzu noticed
that it was a USB storage device, it setup the mount point and everything
(/mnt/camera). I wanted to immediately right click on the desktop and mount
"camera" but it wasn't in the list. Only after a restart of nautilus does
it pickup new mounts. I think this would be a nice "user friendly" sort of
enhancement.
