> for a full system ... does nix still make sense? In many ways, Nix is often "second best at everything". -- Since Nix can be difficult to deal with, it may often be a better choice to use some other tool for any particular use case. e.g. maybe using asdf is a better way to fetch tools (compared to nix-shell), or docker-compose is a simple way of running project-specific services locally (compared to devenv), or fedora silverblue is a simple way of running an immutable OS (compared to NixOS). I'd like to think that the benefits from buying into Nix allow easily getting the advantages. e.g. Nix is a more expressive way to build a Docker image or a VM compared to using a Dockerfile or Packer. For system wide configuration, NixOS allows system-wide configuration declared from a single starting point (possibly composed of several modules), and has those immutable OS benefits like trivial rollbacks.
