Functional package manager where every package is stored in a unique hash-based path (/nix/store/abc...-postgres-16) — atomic upgrades, rollbacks, reproducible builds.
The NixOS distro is described entirely declaratively via configuration.nix (or flakes). "It works on my machine" = "use the same flake.lock". A strong community tradition + a steep learning curve. Major controversies in 2024: governance conflicts, fork movements (Lix, Auxolotl). Competitors: Guix (GNU version), Spack (HPC), classic dnf/apt. AWS Lambda + Replit run Nix internally.
