At first some basics. To use a so called "preseed" file it is good to know what it is. The Debian installation is done with the "Debian Installer", short d-i. This d-i normally is a ncurses based console application that asks you some questions about your timezone, your partition setup, your network and so on. All this questions could be answered trough a preseed file. In this file some or all questions could be answerd.

All our preseed files are placed on a webserver but you should know that it is also possible to integrate the preseed process into a self made Debian installation medium.

The Debian Netinstall CD covers only a minimal system. So if you need more packages like rsync or others you have to connect to the internet. Without choosing a Debian mirror during the setup, the setup could not continue. If you use Debian OpenVZ Servers and Debian based Virtual Private Server at your site, you should use an apt-proxy to cache the downloaded packages.
