Softlanding Linux System

Softlanding Linux System (SLS) was one of the first Linux distributions. The first release was by Peter MacDonald[1] in August 1992.[2][3] Their slogan at the time was "Gentle Touchdowns for DOS Bailouts".

SLS was the first release to offer a comprehensive Linux distribution containing more than the Linux kernel, GNU, and other basic utilities, including an implementation of the X Window System.[1]


SLS was the most popular Linux distribution at the time, but it was considered to be rather buggy by its users. It was soon superseded by Slackware (which started as a cleanup of SLS by Patrick Volkerding) and Yggdrasil Linux/GNU/X, among others.

Similarly, Ian Murdock's frustration with SLS led him to create the Debian project.[4]
