Review on NixOS by Loren Jacobson

I like that everything can be configured via command line or using ncurses (I use this for all my servers). The only problem I have found so far is being able to easily add new packages after booting into an existing system for the first time; however, there are ways around this if you know where they live in /etc/nixos-configuration/* files. If you're looking for something highly configurable then definitely give this distro a try! We've been running multiple virtual machines as well as several physical server instances - some bare metal while others containers. This allows us flexibility when we need more power than our standard VMs provide without needing additional hardware resources.
