Devuan GNU+Linux is a Linux distribution forked from Debian in 2015. The project's primary goal is to provide a variant of Debian without the complexities and dependencies of systemd, an init system and services manager originally developed by Red Hat and later adopted by most other Linux distributions. Devuan's initial beta release was made available in April 2016, together with an upgrade path from Debian 7.0 "Wheezy" and a possibility to switch to Devuan from Debian 8.0 "Jessie". The distribution adopted Xfce as its default desktop. Source: https://distrowatch.com/table.php?distribution=devuan
