Do you have a post on your setup? I'm relatively new to NixOS server management and I've been leaning on NixOps for the coordination bits. I'd love to see what you're doing as it sounds more elegant, efficient, and supported.
I don't have one yet, but I will definitely make one once I make a public release of nixless-agent. At the moment I use a combination of nixos-anywhere (for initial provisioning), colmena (mostly for quick testing/dev setups, because it lets me push things directly to a machine), and nixless-agent (still experimental and going through lots of testing). Ideally my final setup will be just a mix of nixos-anywhere and nixless-agent.
