Had to do some work with SuSE post Novell acquisition for a customer. IIRC the package manager is a bit odd, but I haven't looked at it in what nearly 15 years, so I can't really remember much about it. What I CAN remember involved running packet traces using Wireshark - it was mostly network problems, I think, so nothing to do with SuSE. It was certainly very popular in Europe, though I have no idea what they're doing these days!
