Preseeding d-i

Preseeding provides a way to set answers to questions asked during the installation process, without having to manually enter the answers while the installation is running. This makes it possible to fully automate most types of installation and even offers some features not available during normal installations.

Most of the questions asked by DebianInstaller can be preseeded by setting the answers in the ["debconf"] database. The Installation Guide includes an [ extensive appendix] dedicated to preseeding and includes a complete example. Feel free to add any information that is not covered in the manual to the notes below.


Post here any links you have to example preseed files. Note that using any of these files directly is not wise, as a malicious person could probably come up with values for a preseed file that makes d-i misbehave. Also, the files are downloaded over http, so are vulnerable to man in the middle spoof attacks. The best way to use any preseed file is to copy it to your own local web server or media, and look it over before using it.
