Back when I started in Linux, there was SLS and Slackware. The kernel on the install of Slackware I 1st got was .99pl14. I was slackware until 1995 when I went to Mandrake. I did a brief stink with SuSE but didn't like how different it was from Mandrake/RedHat. When Red Hat went commecial, I became an RHCE and stayed with Redhat derivatives.
