The CD layout is never random, be it in FC5 or nay other release.

You might try
http://article.gmane.org/gmane.linux.redhat.fedora.java/561

Which produced for a *small* subset of Fedora a few years ago:

http://gnu.wildebeest.org/diary/index.php?p=97

(the page may be dead, it's in google cache right now at least)

As you'll see in the example, rpm deps are *not* a simple tree graph,
you have cycles, critical nodes used by many other packages, etc.

And that's not taking into account relations like for example people
interested in the gimp will probably need inkscape too (moreover these
relations depend on the user viewpoint, to take your example some people
will want a pure mysql server, others don't care about the actual db
backend but need perl perl db bindings, etc)
