With the following command we put the files contained in the “net-install” image into the file system under the isofiles DIR if the isofiles DIR does not exist, xorriso creates it automatically. Xorriso allows to extract files from an ISO image and dump into the file system $ sudo apt -y install xorriso Recommended reading: How to download files using curl 2. We will download the “net-install” image that allows a minimal installation, an internet connection is needed since the files are downloaded from Debian repositories. In this post we’re going to use method 1 for unattended installation starting from DebianInstaller/Preseed/EditIso 1. Loading the preseeding file from a webserver.Autoloading the preseeding file from a webserver via DHCP.Load the preseed.cfg file from the network.Add the file boot parameter to the ISO image.Adding the preseed file to the installer’s initrd.gz, link.There are three methods that can be used to execute an unattended installation: Debian is suitable for servers, workstations, mobile devices and embedded systems.ĭebian has a simple and clean installation system which allows installing Debian with little effort as long as the number of installations to be executed is minimal, but as this number grows the installation procedure becomes cumbersome and tedious (Please note that during the installation process it is necessary to answer configuration questions and package selection), for example if we want to install Debian in a lab that has 15 workstations, we need to repeat this process 15 times, which is possible, but if we want to deploy Debian in mass, for example 100, 200, 500 or 1000 installations, it is no longer feasible, this is the reason why the Debian developers have created a system that allows automatic or unattended installations starting from a configuration file (preseed). Debian is a rock solid GNU/Linux distribution with more than 30,000 packages available in its official repositories.
