From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Arch or NixOS? (lemmy.blahaj.zone)

I've been here a week ago already asking if Arch would be fine for a laptop used for university, as stability is a notable factor in that and I'm already using EndeavourOS at home, but now I'm curious about something else too - what about Arch vs NixOS?

I heard that NixOS is pretty solid, as due to the one file for your entire system format you can both copy and restore your system easily whenever, apart from your normal files and application configurations of course.

Are there any major downsides to NixOS compared to Arch apart from the Arch Wiki being a bit less relevant? I'd also lose access to the AUR, but admittedly I don't think I've ever actually needed it for anything, it's just nice to have. Also, since NixOS has both rolling release and static release and you can mix and match if you wanna get packages from unstable or not, I'm not losing Arch's bleeding edge, which is nice.

Let me put it like this: it's about learning curve. Arch is relatively easy to begin with, but NixOS gets much easier the more nix you learn.

What do I mean about that? Imagine having to patch something, which can be the thing. On arch you'd have to replace a package, which could lead to issues and conflicts, whereas NixOS gives you the option to keep two or even more versions of the same library, because it does not rely on your traditional UNIX path.

But with this super power comes a catch. You have to learn a programming language and learn how the nix store operates, which is a pretty high learning curve. Also, NixOS suffers from a governance issue and going by the documentation is like shooting in the dark.

That being said, the best manual for NixOS is GitHub, searching for anything and filtering by the nix language. You'll see a ton of varying systems, be they workstations or servers.

And no matter what all the warnings say, no, flakes aren't EXPERIMENTAL or UNSTABLE, but rather CONTENTIOUS internally. Again: I love NixOS, but they gotta fix their governance issues.
