Linux

The increasing popularity of NixOS can be attributed to several factors that make it stand out among other Linux distributions. Some of the key reasons why people are switching to NixOS include:

1. Reproducibility: NixOS allows for reproducible builds and deployments, ensuring that the same code will produce the same output across different environments[1][2].

2. Easy rollbacks: NixOS has built-in rollbacks, which means that if a configuration change causes the system to be unbootable, it is easy to roll back to a previous working install[1][3].

3. Nix package manager: NixOS uses the Nix package manager, which simplifies package management and system configuration[1].

4. Multiple versions of the same package: NixOS allows users to have multiple versions of the same package installed, which can be useful for testing and development purposes[1].

5. Stability: NixOS is considered a very stable platform compared to other Linux distributions, such as Arch Linux[3].

6. Declarative configuration: NixOS uses a declarative configuration approach, which offers benefits over the imperative approach used by more traditional operating systems[4].

In addition to these features, the recent introduction of the open-source platform flox has made it easier for developers and enterprises to adopt NixOS. Flox expands on Nix's unique approach to package management and system configuration, providing convenience, collaboration, and control throughout the Systems Development Life Cycle (SDLC) [5]. This has led to an increase in the adoption of NixOS among developers and enterprises.

Overall, NixOS offers a combination of stability, reproducibility, and flexibility that appeals to developers and users who want a reliable and customizable Linux distribution.

Here's the straightforward version of why I use it:

1. The entire state of your operating system is defined in a config file, and changes are made by changing the config file. This makes it super easy to reproduce your exact system many times and to know where all the many different configuration elements that describe your system are located.

2. Updates are applied atomically, so you don't have to worry about interrupting the update process and if it fails, the previous state of your system is still bootable. By default every time you change something, you get another option in the boot menu to roll back to.

3. Making container-like sub systems is super easy when you're familiar with nix, so you can have as many different enclaves as you like for different software versions, development environments, desktop setups, whatever without taking a performance hit. Old versions of stuff are very accessible without breaking your new stuff.

4. The package manager has a lot of software and accessing nonfree stuff is straightforward. Guix looks rad, but nix ended up being the more practical compromise for my usecase. I didn't want to have to package a heap of software the moment I made the switch.

I used NixOS for a couple of years. My experience is like this:

1. It is a rolling release (mostly)
2. You write a declarative configuration for your system, e.g., my config will say I want Neovim with certain plugins, and I can also include my Neovim configuration
3. It is stable, and when it breaks it is easy to go back
4. Packages are mostly bleeding edge

It's in no way "everyone", just a vocal minority.

everyone

Now that's what I'd call a stretch...

I keep seeing trends with Linux distribution like teenager looking for new fashion.

I think it’s mostly the very young Linux user who hope from one distribution to the another over and over whereas many just stick with what they got : Ubuntu, Debian, mint, maybe fedora.

NixOS is certainly interesting tho.

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 daily drive GNU Guix instead, and I would strongly recommend any emacs and/or lisp enthusiasts interested in the benefits of functional, reproducible, declarative, and hackable system management to give it a try!

It's insanely stable but you have to have a lot of linux/programming knowledge to do even the simplest things like installing/updating your software or making little tweaks. I played with it for hours the other day and I'm just too dumb to figure it out lol I think it's just a super stable highly customizable distro for power users and a lot of people like that. If you can get over the learning curve it's a pretty powerful and unique os

I've been using it for over a year and love it. A config file for your entire system, and built in rollbacks anytime something goes wrong. One language to configure everything, although in practice that doesn't always work. But I love it.

Some others have started why it works, here is some how. Nixos completely disregards the fhs. Packages don't install to anywhere standard, every package and configuration change gets it's on directory in /nix/store but through smart use of tracking everything there, it symlinks all those files to proper places and sets up the environment for them to know where libraries are.

This is then also why you don't need sudo privileges to install things. Your profile has an environment that is aware of your users packages and configurations, the system itself isn't effected because everything is symlinked.

Then because every update means new directories in /nix/store you can role back to your last configuration because plasma broke something or whatever.

However, it's a LOT to learn. Best place I know of is https://piped.video/watch?v=AGVXJ-TIv3Y&t=0

This guy did a good job for me. Hope this helps!

Because it’s the latest Cool Nerd Thing™ like Arch before it, and Gentoo before that. Most of the people raving about it probably don’t have much use for its features.

SYMLINKS

SYMLINKS EVERYWHERE

(also 6000 packages intalled on my system for some reason lol)

For those who like a video format, I found this introduction quite informative.

nah

didn't have enough time during the last half a decade to learn yet another thing

might be better fit than my current debian setup - but how would I ever know, since my current thing is good enough?

I have been using for years on servers. My lemmy instance is hosted on it.

Although for desktop I had too many issues back in 2019 so I ended up back to Arch Linux and then EndeavourOS

Would be fun to try again to use it on desktop
