As a first thing, do you have latest gnustep-gui and GWorkspace releases?
I did some clean-up there so that code is centralized in NSWorkspace 
(the gnustep class).

I had a look at this and tried to reproduce it on freebsd.
I find it very strange and interesting that unmounting is dynamic and 
mounting not.
Do you have mtab and does it get updated? That may explain something, 
although I would expect it not to be even used
I don't understand how you can get an unmount notification.

On my system the behaviour, with the mount point set in 
SystemPreferences and correct options in /etc/fstab is:
- I can mount a volume in GWorkspace (Check for Disks) and it shows up 
on the desktop with the disk icon
- I can unomunt a volume in GWorkspace (drag to Trash) and it unmounts 
and also disappears from the desktop
- If I mount or unmount from the command line, I get no updates on the 
desktop
- Once mounted from the command line, even calling Check for Disks again 
doesn't show the volume

unmounting should trigger
workspaceDidUnmountVolumeAtPath to be called in
https://github.com/gnustep/apps-gworkspace/blob/master/GWorkspace/Desktop/GWDesktopView.m
While mounting:
- (void)newVolumeMountedAtPath:(NSString*)vpath

When the desktop is shown it goes down to:
https://github.com/gnustep/apps-gworkspace/blob/master/GWorkspace/Desktop/GWDesktopView.m
- (void)showMountedVolumes
which as you see goes thorugh NSWorkspace.

[[NSWorkspacesharedWorkspace] mountedRemovableMedia];

It would be nice that "Check for disks" would update and show disks 
mounted manually, but it does not. That would be good thing, I want to 
check why it doesn't.
