Michaili's Nix Config

My Nix config for my various NixOS nodes. Uses Colmena for deployment.

Some of the highlights & interesting things in this flake:

• The hive NixOS module has mich.meta.ssh options. These allow sharing sharing public SSH keys between colmena nodes, giving every machine a shared SSH known_hosts file.
• Each node may have a special meta.nix file for providing information without evaluating the node. For example, the meta.nix may provide a specific nixpkgs branch to evaluate the node with.
• Various presets nodes can make use of, allowing the right level of granuality
