I make a copy of all home directories in to /etc/backups/ (auto login usernames)
At boot I have it run a script that copies over the user home directory with
the original.
Takes a little longer to boot but was an essential component for a library
system so each patron gets a fresh desktop and nothing is saved. Which is
exactly what we wanted!

Hi Chris,
one good way to implement this would be with an nbd-server cow export
for /home/template-user.
The script that mounts home directories is
/usr/share/ldm/rc.d/X01-localapps, but it would be best to create
another script, e.g. X00-mount-home-template.
I'm available for hire if you need help with it.
Cheers,
Alkis Georgopoulos

Hi
You did not mention your users or anything about how they use the client
devices .
Autlogin on 100 device sounds like a kiosk environment to me. And
preventing changes sounds like a read only filesystem. There is a screen
script in ltsp package called 'kiosk' that creates a temporary session for
each login but you need to configure it to run a specific program or task.
And there are propably hundred others kiosk setups in the internet you can
apply with or without ltsp
"Kiosk" means that clients should have same service and taste every time.
So you create session on the client environment first as a template and
then you configure it to be used (copied) and mounted on tmpfs and cleanup
it on logout or reboot.
first describe what applications your clients use?

Thank you Alkis!

Hi Valtteri,
yes, I've been thinking about using 'kiosk' but it not exactly matches
my profile
to be honest my configuration is a little bit weird ;)
the idea is to have configuration on the server and manage it from the
server (using puppet maybe) so I will not have to rebuild ltsp image
each time it changes
but with the hints from Alkis I think I will be able to achieve what I want
best,
Chris
