Same, I originally had a bunch of RasPi's in my lab running differing versions of Raspbian until I got tired of the configuration drift and finally Nixified all of them. Writing a single Nix Flake and being able to build declarative SD card installation images for all of them makes managing a bunch of different machines an absolute dream (tutorial here[0], for those interested).

The only issue is remotely deploying Nix configs. The only first-party tool, nixops, is all but abandoned and unsupported. The community driven tools like morph and deploy-rs seem promising, but they vary in terms of Flakes support and how much activity/longevity they seem to have.

I can vouch for deploy-rs. Used it for years without issues. Flake support is built in and activity is pretty good.

Im really happy with nixinate if you havent tried it. Basically does the bare minimum so theres no real concern over continued development.
