NixOS is the only[1] Linux distribution that feels like it is build around Free Software. Meaning upstream Git repositories can be treated as first-class citizen and installed directly without convoluted binary packaging system (that still exists in the background, but only as cache to speed up build times). Nix also makes it very easy to upgrade, downgrade, side grade, patch, override dependencies or otherwise change packages, or even just keep multiple versions of the same software around. Something many other distributions still struggle with or make completely impossible with the distributions own tools. Even the act of installing software in Nix becomes somewhat unnecessary, as you can just run software straight from the Git repository.

And best of all, it’s all based on a very simple and transparent packaging system, if you ever used GNU stow, kind of like that, it’s all held together with a bunch of symlinks and some environment variables. No contains, no ostree, none of those ugly workarounds, just plain old Unix stuff that you can find and grep through as much as you like.

Simply put, NixOS puts the joy back in Linux, while other distributions like Ubuntu try to actively trash their reputation with a proprietary App store and others like Debian just stagnate around and are still stuck with the same old packing system that was state of the art 25 years ago and hasn’t improve much at all since than. NixOS just provides a dramatically cleaner and simpler approach that also happens to be vastly more powerful.

Another cool thing, if you don’t wanna switch distributions just yet and reinstall the full NixOS, you can just use the Nix package manager itself on whatever distribution you are already using.

[1] There is also GNU Guix, which is basically a reimplementation of Nix with Guile/Scheme

I switched around one and a half years ago. I must say, there are some hurdles to using NixOS. Mainly I dislike that it always takes around 20 times the effort to start and project. You make up for the initial time investment, because you end up with a far more stable setup, but still it does take some willpower to get things started.

They don’t know about Debian stable.

I will switch as soon as I can get proprietary Nvidia drivers to work on my laptop.
