A NixOs user group.
NixOS is a Linux distribution based on Nix, a purely functional package management system. NixOS is an experiment to see if we can build an operating system in which software packages, configuration files, boot scripts and the like are all managed in a purely functional way, that is, they are all built by deterministic functions and they never change after they have been built.
