ArchLinux

Arch Linux is an independently developed, i686/x86-64 general purpose GNU/Linux distribution versatile enough to suit any role. Development focuses on simplicity, minimalism, and code elegance. Arch is installed as a minimal base system, configured by the user upon which their own ideal environment is assembled by installing only what is required or desired for their unique purposes. GUI configuration utilities are not officially provided, and most system configuration is performed from the shell by editing simple text files. Arch strives to stay bleeding edge, and typically offers the latest stable versions of most software.

Arch Linux uses its own Pacman package manager, which couples simple binary packages with an easy-to-use package build system. This allows users to easily manage and customize packages ranging from official Arch software to the user's own personal packages to packages from 3rd party sources. The repository system also allows users to easily build and maintain their own custom build scripts, packages, and repositories, encouraging community growth and contribution.

Arch Linux uses a "rolling release" system which allows one-time installation and perpetual software upgrades. It is not generally necessary to reinstall or upgrade your Arch Linux system from one "version" to the next. By issuing one command, an Arch system is kept up-to-date and on the bleeding edge.
