Limiting GNOME/KDE to just those mounts listed in /etc/fstab provides a 
mechanism of access control.  If GNOME/KDE allowed user mounts of any 
device, then it would become possible for users to mount umounted system 
volumes.  Using fstab also makes it possible for GNOME/KDE to mount items 
with mount options (sync, mode limits, quotas, etc.) and just rely on the 
system to get it right, rather than having system-specific, parallel mount code.
