It's way better than the previous status quo: now, more or less whatever distro I'm on, there's one command which answers that question directly, not a process of guessing how this system happens to be set up. You can guess and grep through most any kind of problem, but I don't see why anyone would want to do it as anything but a last resort, and to me that fits '37 easy steps' far more than the 1 consistent step in these replies (notice how none of them say 'oh, but on debian...'?).
