Linux Distributions Overview

A guide to the main Linux distros, their families, package managers, and how to choose one

Overview

Linux is not a single operating system — it is a kernel around which thousands of distributions have been built. A distribution (or distro) bundles the Linux kernel with a package manager, init system, desktop environment, and default software to create a complete, usable OS.

Choosing a distro means choosing a philosophy: rolling releases or stable snapshots, binary packages or source compilation, curated defaults or complete freedom. Understanding the family tree helps navigate those choices, since most distros inherit tools, repositories, and conventions from a common ancestor.

Distribution Families

The table below covers the distributions present in the family diagram above.

Debian

The oldest actively maintained major distro (1993). Renowned for rock-solid stability, the largest community-maintained package archive (~60,000 packages), and its strict free-software policy. Uses APT with .deb packages.

The Debian family is the most widely used base on servers, desktops, embedded systems, and live/security distros alike.

Arch Linux

A rolling-release distro that ships the latest stable software the moment it is packaged. No installer GUI, no predefined desktop — users build exactly what they need. Uses pacman with .pkg.tar.zst packages and the AUR (Arch User Repository), the largest community software source on Linux.

Derivatives typically add graphical installers and curated defaults on top of the Arch base.

Red Hat / Fedora

Red Hat (founded 1993) pioneered commercial Linux. Fedora is the upstream community release where new features land before they stabilise into RHEL (Red Hat Enterprise Linux). Both use DNF with .rpm packages. Rocky Linux and AlmaLinux are RHEL-compatible rebuilds maintained by the community after CentOS was discontinued.

SUSE

Originating in Germany (1992), SUSE produces both SUSE Linux Enterprise (SLE) for enterprise workloads and the community openSUSE project. The flagship tool is YaST, a comprehensive system management suite. Package manager: zypper with .rpm.

Gentoo

A source-based distro where every package is compiled locally from source using the Portage build system and emerge command. Extreme customisation and performance optimisation at the cost of build time. Derivatives like Redcore add binary caching to lower the barrier.

Independent

Some distributions reject inheritance entirely and establish their own tooling:

  • Alpine Linux — ultra-lightweight (~5 MB base), built on musl libc and BusyBox instead of the GNU toolchain. Favoured for container images and embedded systems due to its minimal attack surface. Package manager: apk.
  • NixOS — declarative, reproducible system configuration via the Nix package manager. The entire OS is described in .nix files; rollback to any previous state is always possible.
  • Slackware — the oldest surviving Linux distribution (1993, Patrick Volkerding). Deliberately minimal: no automatic dependency resolution, no complex tooling; uses pkgtool with .tgz packages.
  • Solus — desktop-first independent distro, historically known for the Budgie desktop and the eopkg package manager.
  • Void Linux — independent, rolling, using the XBPS package manager and the runit init system instead of systemd.
