A powerful package manager for Linux and other Unix systems that makes package management reliable and reproducible. Nix provides atomic upgrades and rollbacks, side-by-side installation of multiple versions of a package, multi-user package management and easy setup of build environments.

NOTE: This package only provides the nix binaries. One still needs to setup directories, environments variables and configuration files to use nix as described in the nix manual. The package nix-setup-systemd provides such a setup using systemd mechanisms, also see /usr/share/doc/nix-bin/README.Debian.
