I’m wanting to create a centralized repository to keep base images of operating systems to be installed on new laptops or workstations bought/used in my household with my local CA already installed, configured to authenticate with my local FreeIPA instance, network configurations already configured, etc.

What do you all use to accomplish this? I’m only free/libre/open source software for my home lab, so that’s a requirement as well.

Ideally I’d like to be able to buy a computer, flash the latest and greatest from my repository onto a bootable thumb drive, install onto the computer, and be ready to go without any further configuration.
