That's exactly the point. It's so complex that it's impossible to track down (and thus fix) the cause of any of its problems. What works for you does not work for someone else, and vice versa, because of some seemingly unrelated difference in how their system was built or configured (usually by their distro, often even as a result of difference between upgrade-vs-fresh install).
