Use instutils autoinstall

The reference documentation only supports some default use-cases for the unattended installation process. You won't be able to build more complex configuration such as RAID-based installations using this reference. Under-the-hood, the installer uses curtin.

The linked documentation can help you further build complex installations, such as those which use RAID. I think the curtin syntax is a bit tedious and fortunately it is probably not required to learn curtis and piece together more complex configurations by hand. There is a nice quality-of-life feature that takes care of this. With a regular PXE-based installation, we use the 'netboot' installer, which consists of a Linux kernel and an initrd image containing the actual installer.

This package is about 64 Megabytes for Ubuntu The new Subiquity installer for Ubuntu It is not provided anymore. Instead, you have to boot a 'live installer' ISO file which is about 1. This process is documented here with detailed how-to steps and commands. And I assure you, MB is not enough.

From what I read, some people tried to use it but it didn't work out. As I undertand it, the curent status is that you can't install Ubuntu Server This probably affects older and less potent hardware, but I can remember a time that this was actually part of the point of running Linux.

I've verified this with a system with only 1 GB of memory. Now let's go back to the actual automation part of Autoinstaller. If we would want to automate our installation, our PXE menu item should be expanded like this:.

In this case, the cloud-init folder - as exposed through an HTTP-server - must contain two files:. The user-data file is the equivalent of a preseed file, but it is YAML-based instead of just regular plain text. Personally, I like to keep the unattended installation as simple as possible. I use Ansible to do the actual system configuration, so the unattended installation process only has to setup a minimum viable configuration.

I used this configuration to specify a particular mirror for both the installation process and for the system itself post-installation. Successfully tested on vanilla Ubuntu Choose Ubuntu The system requirements depend on the flavour of T-Pot you intend to run.
