Nix package manager

Nix is a package manager that pioneered Functional package management which addresses the criticisms of traditional Unix systems while making it as a specialized tool for Reproducible research. Holistically, Nix is made up of at least four components: the store, the language, the derivations, and the sandbox.

• The store is a immutable centralized location where all of the outputs are placed.
• The derivations are essentially build instructions.
• The language (also called as Nix but we'll refer to it as Nixlang) is a domain-specific language for creating derivations.
• The build process can be locked in a sandbox, improving the reproducibility of a setup and lowering the attack surface for a malicious package.
