Re: Nix, how do you run a service for which there is not a nix package? Or what if you need to build a service differently from how it's packaged for nix? For instance, you want a build of OpenLDAP with Argon2 or bcrypt support.

You write a nix package, modify other nix packages in nixpkgs, write overlays, and so on. Nix can package any software, build containers or OS images, the sky is not the limit. But first you have to invest (estimated) 2-3 weeks to learn it properly. Hell of a learning curve.
