@rebtoor NixOS is very good for configuring services, because you have all configurations in one or few files, and you can use code for factoring out common configurations with only few changes in parameters. You can iteratively improve all the settings. Very nice and funny.

But now I had to packages some Common Lisp library, and it will be a "nightmare" because I had to become an expert of the Common Lisp way, of the Nix way and solve some problems. So if you are using it for development, at the first problem, you can easily spend a day or more for solving it, because the entire world is not following the Nix way.

NixOS community is worderful and it is very easy to contribute. It is the only distro where I submitted some patches. Very smooth process.
