[idea] Troubleshooting Guide

On Micosoft Windows, there's a "troubleshooting guide" thing that
poinks up when the network fails to work, etc.  It's heirarchial
document with questions that click down to more precise questions and
so on down to answers, to guide the user to a problem solution.

What if we had something like that for Linux, in some standard
document format, so that any package could drop it's trouble shooter
into the directory for them?
