Rob, Correct. It was added in 8.10. But maybe you could have a quick look (in a VM maybe?) and replicate the functionality for your 8.04 install?

Re: [ubuntu-uk] Clearing home directory at logout
2009/1/29 Rob Beard r...@esdelle.co.uk: Actually having a bit of a play I think I might have found a workaround. I ended up installing the GDM Watchdog which checks for when a user logs out (or alternatively turns off the client). It then closes all the users processes so in there I've put in a test command which works and runs as the logged in user. Hopefully I can put together a simple script to empty the home directory and unpack a tar archive back into the directory. Not ideal but as I'm on a tight schedule (server is being installed on Saturday and goes live on the 7th Feb) it looks like it'll have to do. I'll just have to try and find a more elegant solution afterwards. Rob, debian's LTSP package uses LDM rather than GDM to control logins. I don't know if Ubuntu is the same? Have you tested the script on the LTSP machines yet? For LDM, the LTSP howto describes different scripts that can be executed on startup, login and logout. It also has a section on customising the screensaver, which might be useful (on debian it locks the screen after a few minutes, which isn't always helpful).

Public domain, do as you like.
Slight bash optimisation included below...
[snip]
username=$1
if [[ $username == ]]
then
username=$defaultusername
fi
username=${1:-${defaultusername}}
This single line replaces both the assignment and the 'if..fi' block.
The unfortunate bit about this replacement is that no one understands
it without reading the bash man page! :-)
