NixOS 21.11 “Porcupine” is here, but default Nix version remains at 2.3 point release rather than Nix 2.4.

NixOS is a Linux distribution that is entirely different than what one can expect from a regular Linux distro. It’s a Linux distribution which takes a unique approach to package and configuration management, because it’s built around Nix tool. So let me first explain what the NIX tool is.

NIX is a package manager and it could be used on any Linux distribution on top of the distribution package manager. To put things simple, NixOS is an operating system, and Nix is a package manager.

Now, everything in NixOS down to the kernel, is built by the Nix package manager with a declarative functional build language. The whole system configuration: fstab, packages, users, services, firewall, etc., is configured from a global configuration file that defines the state of the system.

Furthermore, NixOS is probably even more complex than Arch Linux or Gentoo, that lacks a graphical user interface for managing installations. So, if you are new to Linux and you are not comfortable typing commands into a terminal window, probably NixOS is not distro you want to try any time soon.

Yesterday the NixOS development team announced the release of NixOS 21.11 “Porcupine” operating system. So let’s see what’s new.

What’s New in NixOS 21.11

NixOS 21.11 places a focus on stabilizing the core system, but it’s a little disappointing that the default Nix version remains at 2.3.16, and Nix has not been updated to version 2.4. The reason – regressions in non-experimental behavior.

The good news is that NixOS 21.11 allows you to upgrade to Nix 2.4. You need to use the nixos-unstable branch or set the nix.package option to either of nixFlakes or nix_2_4 packages.

Additionally, the distro includes many changes and upgrades that will help keep users in front of the latest technologies. Some of them are PHP 8.0, Python 3.8, PostgreSQL 13, spark 3, an so on. On top of that Bash shell defaults to major version 5 and iptables now uses nf_tables backend.

:: More ::

The Nix package manager concept is great but somewhat ironic is the new NixOS 21.11 release not even shipping with the latest Nix package manager version due to known regressions.

NixOS 21.11 released yesterday and rather than shipping with the latest-and-greatest Nix, it's being held back to the latest Nix 2.3 point release by default rather than Nix 2.4. Holding up the default version of Nix was done as "Nix has not been updated to version 2.4 due to regressions in non-experimental behavior."

Nix 2.4 focused on delivering improved error messages, various command improvements, new built-in functions, support for x86_64 micro-architecture feature levels, and a variety of other improvements. Nix remains a novel and very interesting package management solution.

On the operating system side, NixOS 21.11 has switched from iptables to using nf_tables, its KDE Plasma packaging now fully works on Wayland, better support for LXD, and a variety of new services are now available. There is also many updated packages including the likes of PHP 8.0, Python 3.9, PostgreSQL 13, Spark 3, Bash 5.0, GNOME 41, systemd 249, and many more.
