Crafting Systems on NixOS: Part 1

In this live series, I’m rebuilding my entire NixOS system configuration from the ground up. This setup powers my daily driver laptop, backup machine, and a network of self-hosted servers I use every day for a few years now. I’ll walk through how everything fits together, what I’ve learned so far, and how I plan to evolve it over time.
