[gdm-list] Logout script does not always complete

[Jaap Winius <jwinius umrk nl>]

Hi folks,

All of my workstations run Debian squeeze and gdm with login and  
logout scripts. The latter is a bash shell script, called from  
/etc/gdm/PostSession/Default, and is located on the file server,  
available via NFS. It's supposed to create a "logout file" in a  
directory on the file server.

Usually, everything works fine. But, every once in a while, and only  
when a user elects to logout and shut down the workstation at the same  
time, that logout file is not created. I assume this is because the  
network connection is stopped before the logout script has a chance to  
complete.

Can anyone suggest a good way to ensure that my logout script always  
completes before the network connection is stopped?

Thanks,

Jaap
