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.

Reproducibility. If I'm spending months configuring my setup then I want it to stay exactly the same and easily rebuildable even if I switch/upgrade my computer. NixOS is the only answer.
I would 'free but folks need to learn some Nix basics before the jump in headlong into bad community recommendations like starting with flakes. It’s hard to just drop into Nix without some commitment.
This! I've got 7 machines running NixOS already and using Linux on so many machines is only manageable with the reproducibility NixOS provides. Whenever I lay my hands on a new server, PC, laptop, tablet or phone, I just add a few lines for it in my config, run a single nixos-anywhere command and it's good to go. Syncing changes is also just two commands: git pull && nh os switch. Been using NixOS for a year and a half and it still can'st stop to amaze me
