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.

I've used Arch as my daily for so many years now, it is a little tricky moving from imperative to declarative configuration. I'm treating my NixOS machine more as long term maintenance, so I'm not using the most bleeding edge packages. You can do that though by pointing to
nixos-unstable.I plan on using flakes for pinning and home-manager for writing
~/.configconfigurations, but I don't think I really need it, more just to learn how. With home-manager, I could rebuild this machine from scratch (including individual application preferences/settings) just with the backed up configs. I can at any point rollback to any saved previous generation though, too, just by restarting the machine.I've really been impressed with it though. To the point, I will probably be moving my Arch DIY router over and converting it to NixOS.
Thanks, maybe I'll give it a shot soon.
