[LightDM] How to setup guest account

Hi,

we are running a netboot environment with root on NFS with LightDM as display 
manager and XFCE as desktop, all on Debian sid.

That works great; however, I am all puzzled about how to set up the guest 
account. What I want is a guest account that sets up a complete user home in 
tmpfs (e.g. /tmp) on login and behaves just like a normal account from there 
on. I believe that LightDM supports that, but I have a few questions:

 - What is the name of the guest user?
 - Do I have to create the guest user as a system user first?

What I _believe_ is that I have to create a system user that is called - 
exactly - "guest", and write a guest-session script that does the user home 
setup. However, I do not find documentation about whether this is correct or 
not.

Any hints, please?

Cheers,
Nik
