Re: why there is a problem?
RPM files are a much bigger problem than config files, and the advantage of the good package managers (like rpmdrake) is that they try to automatically install or remove packages to satisfy dependencies (they do fail often). The idea of going to a command line and opening a file scares many people. If there is a nice gui, the users can make modifications and be sure that they will not mess up the program by typing something wrong. before you start talking about how easy it is (and I would agree that it can be easier) remember that when you go to the general public, many people don't want to spend any time learning about their computer. With a gui, all of the available options can be listed for the user to pick from, and the user doesn't need to search for the file to configure.
