Callout not called when USB disk removed?

[Peter Valdemar Mørch]

I have an external USB drive. The callout gets called/run on insert, but 
not on removal of the USB drive. Where did I go wrong? :D

details:

 > cat /etc/hal/fdi/policy/devLinks.fdi
<?xml version="1.0" encoding="UTF-8"?> <!-- -*- SGML -*- -->

<deviceinfo version="0.2">
   <device>
     <match key="info.udi" 
string="/org/freedesktop/Hal/devices/storage_serial_Maxtor_4_D040H2_1200E000022237521">
       <append key="info.callouts.add" type="strlist">devLinks.pl</append>
     </match>
   </device>

All /usr/share/hal/scripts/devLinks.pl does is touch a file in /tmp. The 
file is touched when I insert the usb drive, but not when I remove it. I 
can see from

lshal --follow

that hal does notice both insert and remove, but the callout is not called.

In 2004, Sjoerd Simons (sjoerd at luon.net) posted
"[patch] Do callout when optical device is removed", patching 
hald/linux/block_class_device.c. The 0.5.7 changelog metions that this 
was renamed to volume_remove_from_gdl in 2004 but neither of these 
functions are present in the code any longer. (Looks like major 
refactoring has taken place along the way.)

Should I expect my callout to get called when I remove the USB disk? Is 
there any way I an make that happen?

Sincerely,

Peter
