NAK - if a fake public key were distributed then packages signed with
the fake key would be matched, allowing full access to install crap in
your machine.

And packages signed with any valid redhat key would be
Which is what I said. Thus it would be noticed immediately.

The public key really must be distributed in a secure manner.
The standard way is to use certificates, but the update process isn't
set up for this AFAIK, and in any case certificates have to be
signed ... I'm sure suggestions are welcome as to how to accomplish

Suppose I have NO RedHat installed. I have no working computer near
me. I want to install Fedora 9. How do I establish the ability to
subject the packages to tests for being properly signed, that the
key used in the test is correct, and that I am reading and updating
from a legitimate mirror?

If this can be done once in an initial install situation it can be done
again in an update situation using the same mechanism.
