I used SLS and it did suck. I almost surely used one of the first slack distros and never really looked back. I ran redhat a long time (work) but it was always slack for me, and my OLD slack server was the one that was always there to run the show when the redhat machines were choking on dependencies or some other nonsense.

Back in the old days, some guy in the #linux channel had "NCSA Mosaic is GOD" as his /quit message. I say "Slack + screen" is God, screw X!
