NixOS/nix — Nix, the purely functional package manager

Description and use

Nix is a purely functional package manager that enables reproducible, declarative, and atomic software builds across Linux, macOS, and other Unix-like systems. By treating packages and system configurations as immutable expressions, Nix ensures reliable rollbacks, side‑effect‑free upgrades, and precise dependency tracking. The project powers the NixOS Linux distribution and can be used independently to manage development environments, CI pipelines, and container images.

Problem
