Arch is something a fairly non DIY user can easily conquer and use for many years and it will just work. As long as they don't choose to do anything exotic, they can use it basically forever.<p>NixOS is nothing like that, there's limited docs, the docs are sometimes just RTFM that links to another RTFM and oh yeah don't be afraid of breaking userspace because userspace is doing something wrong. It's fine for some of us who can of course get shit done.<p>Ultimately, I think some subset of Arch users who really wanted to be Gentoo users but weren't because "drama" and then NixOS scratches that itch.
