AntiX
AntiX is a Linux distribution of the Debian family which was created with older hardware in mind. Unlike Debian, it does not use systemd for initialisation. It runs well on limited memory and includes drivers for a number of old video cards. Both 64-bit and 32-bit versions are available.
It emphasises small footprints and therefore does not support large desktop environments but instead uses a choice of window manager-based desktops including fluxbox and iceWM. For browsers, it provides the lightweight Dillo and the graphical version of links as well as firefox. LibreOffice is available but is no longer included on installation images because of its size.
AntiX uses the Debian package management system apt and the Debian repositories alongside its own repositories for AntiX-specific software and for systemd-free versions of standard software such as cups.
