Artix Linux is a fork (or continuation as an autonomous project) of the Arch-OpenRC and Manjaro-OpenRC projects. Artix Linux offers a lightweight, rolling-release operating system featuring the OpenRC init software. (An alternative spin features the runit init software.) Three editions of Artix are available, a minimal Base system, an edition featuring the i3 window manager and an edition which runs the LXQt desktop.

Artix Linux is a rolling-release distribution, based on Arch Linux.
It uses OpenRC, runit or s6 as init because PID1 must be simple, secure and stable.
