Automatic Installation (a la kickstart)

[Yann Rouillard <yann@pleiades.fr.eu.org>]

Hi,

I would like to know how I can set up automatic installation with Debian 
Installer.
I found several mails on this subject but none of it explains precisely 
how to achieve this goal (i.e. I don't know how to put a file in a 
preseeding udeb).

Thanks for your help.

Yann
