I want to mount a ramdisk and have it show up in places, but not on the desktop. When I look at the desktop folder from within nautilus, the ramdisk does not sure up. When I look at the desktop from the desktop however, the icon shows up. I understand that this is due to gconf, so I run gconf-editor to prevent volumes from showing up on the desktop.
I can run:

gconftool-2 -t bool /apps/nautilus/desktop/volumes_visible -s true

to show the icons, and run:

gconftool-2 -t bool /apps/nautilus/desktop/volumes_visible -s false

to hide the icons. 

What I want to do is hide some of the icons, for example, I would like for flash drives to show up on the desktop, but not ramdisks. What I mean to say is that I would like to have  

gconftool-2 -t bool /apps/nautilus/desktop/volumes_visible -s true

set and be able to hide volumes from the system still.


The ramdisk I had mounted was done by following these steps:

First, I edited my /etc/fstab to include this line:

ramdisk		        /dev/ramdisk            tmpfs  	gid=5,mode=620	0 0

I then ran:
sudo mount -t tmpfs /dev/ramdisk /mnt/ramdisk
using the /mnt/ramdisk directory I had already created.
The drive mounted, but I couldn't figure out a way to hide it!
I tried editing /usr/share/hal/fdi/policy/10osvendor/20-storage-methods.fdi by adding: 

	<!--Ignore tmpfs/ramdisk drives -->
        <match key="volume.fstype" string="tmpfs">
	    <merge key="volume.ignore" type="bool">true</merge>
	</match>

I did this because I expected my ramdisk to be ignored since it had a fstype of tmpfs. I based it off of another clause in the same file which was for hiding recovery partitions on HP desktops of type vfat. Shown below is the clause I mimicked: 

        <!-- HP ships desktops with a recovery partition -->
        <match key="volume.fstype" string="vfat">
	  <match key="volume.label" string="HP_RECOVERY">
	    <merge key="volume.ignore" type="bool">true</merge>
	  </match>
        </match>




Assuming my clause was accurate based on syntax, I restarted my machine however, upon reboot, I still did not find that my ramdisk had disappeared. This is somewhat a continuation of this bug: https://bugzilla.redhat.com/show_bug.cgi?id=400351
from Fedora 8, however, it still applies to me, who is using Redhat Enterprise 5.

Basically, I would like to have ramdisks hidden from showing up on the desktop and have flashdrives and external hard drives show up on the desktop. How can I do this, and am I following even remotely the correct procedure for doing so?
