Debian preseeded setup

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.

Now it is good to know that if you do not answer a question or if a question pops up which is not in the preseed file, the d-i wait until you give a right answer. So it is a really good thing because you could leave some thing open and use the same preseed file for different hardware boxes e.g. one hardware have one network interface, another hardware has four network interfaces.

Also it is good to know that you can use the preseed file to answer questions from any Debian package which is using the debconf interface, for example postfix.

Starting the preseed setup

Simply download the Netinstall CD from a Debain mirror.
