Yes, Nix profiles are package manager (or system level) alternative to virtualenv, etc. They can be used to give different evironments, be it development or production. Actually, your system is a "system" profile. You update profiles independently from each other. Example of collection of such environments: https://github.com/chaoflow/skel/blob/master/.nixpkgs/config.nix https://github.com/chaoflow/skel/blob/master/.nixpkgs/config... I'll mention examples with NixOps and how I've used it in practice. Good call about "development workflow", I'll think about how to explain that in minimal words.
