By policy, there are things that rpm scriptlets should not do.  But if
you created an rpm which had a %post section containing rm -rf /, rpm
would run it AFAIK.

The Fedora dir contains just what is included on the DVD media.  The
Everything dir contains all of the packages available.  Everything is
a superset of Fedora.

You would need to create a trojan package and get it onto the mirrors,
signed by the Fedora package signing key for a particular release.
This is not an easy task, as the keys are held pretty tightly, with
very limited access (if a handful of people can sign packages, I'd be
surprised).
