Linux

I was not trying to cause any offence. Mad respect for SUSE. As I hinted, I was simplifying. It is hard to talk about this stuff both accurately and concisely.

SUSE is certainly not a Fedora “fork” as Fedora Core was not even conceived until considerably later. Neither was OpenSUSE really. So you cannot take my first comment too literally.

Let’s remember how early SUSE was in the Linux timeline. Back then, everybody was downloading their software from the same FTP sites. A huge component of what made a Linux distribution different from an FTP repo was the package manager and those came from Red Hat or Debian.

The provenance of SUSE is also a bit complicated as the first versions were explicitly based on Slackware. Starting with 4.2 ( a made up version number meant as a nod to Douglas Adam’s I think ), SUSE became Jurix + RPM. So it is a Jurix fork in that sense. However, I cannot imagine more than a handful of people ever used Jurix. I would be interested to know the numbers. In contrast, in terms of both users and industry awareness, Red Hat was THE Linux distro back then.

Red Hat was certainly an influence on SUSE beyond the source code. Red Hat and SUSE were not just communities or collections of code. Red Hat and SUSE were two of the earliest company backed distros. Both had clear commercial ambition. It is no accident that they both evolved into explicitly “enterprise” subscription products flanked by explicitly community distros. SUSE and Red Hat were more like each other than they were like other Linux players ( especially in the days before Ubuntu ). It is not far wrong I think to think of SUSE as the Red Hat of Europe with Red Hat attracting American infrastructure giants like Oracle and SUSE becoming the platform for big European players like SAP.

SUSE is not a fork in the sense that we are going to find an import into the source code version control system from Red Hat ( other than RPM itself of course ). Again though, we should note that this is not how stuff worked back then ( see comment about FTP sites ).

RPM could have been a purely technical choice for SUSE but, in my view, they had a clear desire to use Red Hat as a template more broadly. That is what I meant by saying SUSE could be seen as a fork while also acknowledging that the statement is not quite fair ( or perhaps more that it is not technically accurate in the strictest sense of what the work fork means even if it instructive as a historical perspective ).

Your infographic shows that suse was rebased off jurix and redhat after it stopped being Slackware based.
