Well, aMule is a multi-platform application. What works on Windows is completely different on a Mac or on Linux, BSD, Solaris, IRIX, you name it. Even Linux distributions differ among themselves. I doubt a simple GUI for such things will be an official part of aMule. We are glad to accept user contributions for such tools, though.
Anyway, I believe Suse uses sys-v style init files and should be compatible or at least similar to red hat.
