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.

If you already using EndeavourOS, you are already using Arch. So it is a very odd question. You could remove the maybe 12 EndeavourOS packages and comment out the EndeavourOS repositories if you want to go truly vanilla Arch. Out of the 80,000 packages Arch makes available to you, about two-dozen are EndeavourOS specific. Once installed, they are effectively the same OS.

So, you are just asking if it worth it for an Arch user to move to NixOS.

From what I can tell, the killer feature of NixOS is rolling out a config to multiple machines. Is that worth a switch to you?

The other big attraction of both Arch and Nix is the huge package library but if you do not use the AUR today, that does not matter to you either.

The killer feature is declarative system management. Reproducible systems is just one of the resulting properties. You want to just try out KDE for a week coming from gnome? Good luck getting rid of all the bloat when switching back on arch. You want to run a program once but not necessarily have it installed on your system? You can do that with nixos. You messed something up and your system now doesn't boot? You can go back to a previous iteration with nixos, no need to find your liveUSB to start messing with chrooting and stuff. Ever find yourself asking where the configuration file for is so you can edit it? The answer is /etc/configuration.nix Ever had to merge older configs with newer ones because the software updated? (If no, you haven't been using arch for long) why would you need to do that? You declaratively specified how you want your system to behave and nixos will figure out how to translate that to the new config.

And that's just the "killer" features I use on a day to day basis
