The Nix package manager employs a model in which software packages are each installed into unique directories with immutable contents. These directory names correspond to cryptographic hashes that take into account all dependencies of a package, including other packages managed by Nix. As a result, Nix package names are content-identifying ...
Nix package manager: Nix is a package manager for Linux and other Unix-like systems that makes package management reliable and reproducible. It 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;
A package manager or package-management system is a collection of software tools that automates the process of installing, upgrading, configuring, and removing computer programs for a computer in a consistent manner. [1] A package manager deals with packages, distributions of software and data in archive files.
NixOS is a free and open source Linux distribution based on the Nix package manager.NixOS uses an immutable design and an atomic update model. [6] Its use of a declarative configuration system allows reproducibility and portability.
Inherited from the design of Nix, most of the content of the package manager is kept in a directory /gnu/store where only the Guix daemon has write-access. This is achieved via specialised bind mounts, where the Store as a file system is mounted read only, prohibiting interference even from the root user, while the Guix daemon remounts the Store as read/writable in its own private namespace.

The Writing R Extensions manual [7] specifies a standard directory structure for R source code, data, documentation, and package metadata, which enables them to be installed and loaded using R's in-built package management tools. [3] Packages distributed on CRAN must meet additional standards.
