In recent years, global political changes have put digital sovereignty at the forefront of the discourse again. While governments focus on the industrial side of the equation, this talk will explore how the more mundane and smaller scale practices of homelab and self hosting matter, and how it relate to the subject of sovereignty. It will present various french initiatives (such as CHATONS, FFDN, etc) but also global communities around self hosting and some surprising motivations. We will also explore how free software communities can help by following some best practices in their project (like the best practice to distribute binaries, configuration, etc) .
