Customized and derived distributions

While the first few years, S.u.S.E. Linux was indeed based on Slackware,
the distribution was really switched to Florian LaRoche's jurix with him
being hired and the adoption of rpm by S.u.S.E. in the mid-90s. S.u.S.E.
Linux since then is much more a jurix derivative than a slackware one.
