Nix and NixOS

Configure an OS with a package manager?! How??

By Sam Hatfield

NixOS is a linux distro with unique repository and dependency features.

In this talk, Sam will discuss Nix, the functional package manager used in NixOS. We will focus on Nix's unique aproach to package management, and how that completely changes how we can manage operating systems.

NixOS is an independently developed GNU/Linux distribution that aims to improve the state of the art in system configuration management. In NixOS, the entire operating system, including the kernel, applications, system packages and configuration files, are built by the Nix package manager. Nix stores all packages in isolation from each other; as a result there are no /bin, /sbin, /lib or /usr directories and all packages are kept in /nix/store instead. Other innovative features of NixOS include reliable upgrades, rollbacks, reproducible system configurations, source-based model with binaries, and multi-user package management. Although NixOS started as a research project, it is now a functional and usable operating system that includes hardware detection, KDE as the default desktop, and systemd for managing system services.

Monthly Meetings

The Saint Louis MO, STL Linux Users Group (STLLLUG) meets monthly to learn and talk about Linux. This GNU/Linux Users Group usually holds its meetings on the third Thursday of every month. Meetings are free, public and open to all.

We will continue with our great restaurant location. You can come early, or not; but, we should all wait to order food and drink at the same time.

We start gathering by 6:30PM and at 6:45PM we start with introductions, announcements, current events of interest, and a general CALL FOR HELP segment. Then we will go into the presentation of our main topic, sometime around or after 7:00PM.
