Nix has just been removed from the university computers here. They admit it’s nice, but the new (smaller) team just doesn’t have the time to create the packages themselves. That’s the flip side.
NixOS needs what is IMO the killer feature of Arch: the wiki.
Comprehensive documentation on not only the OS but the additional packages that we use is what drew me to Arch, and the thing that makes me swear in frustration whenever I have to use Ubuntu/Debian.
NixOS is an excellent OS that has the promise of being every bit as hackable as Arch, but far more stable. Problem is, configuration is very different and needs extensive documentation to reduce that friction point.
The Arch wiki is pretty distro-agnostic (barring package names and
pacman
specific stuff). I’ve been distro-hopping for past decade and I’ve always used it as a reference for setting things up.The Nix package manager got ported to OpenBSD, so that part of NixOS must be excellent.
