A script to create a custom Debian ISO that has its installation options preseeded.
This script creates a custom AMD64 ISO image of Debian Bullseye, the current stable release of Debian. The generated .ISO file contains the installation options, such that fully automated installation is possible without the need to go through the installation process manually. See the docs for more info about preseeding installation options.
Clone this repository:
git clone https://github.com/TvanMeer/debian_preseed.git
Edit the preseed.cfg file to your liking.
Then create the custom ISO image:
cd debian_preseed
sudo chmod u+x create_iso.sh
./create_iso.sh
The directory debian_preseed will now contain the file debian-11.3.0-amd64-modified.iso.
