Unsigned packages in yum in FC4T1

[Pete Zaitcev <zaitcev redhat com>]

Hi, Guys:

Does anyone have an idea what is up with all the "unsigned packages"?
I have installed FC4T1, but running "yum update" on it gets stuck
with this:

........
Downloading Packages:
unsigned package gdb-6.3.0.0-1.9.i386.rpm

(it's not important which package is this, there are literally dozens
and dozens of these)

Seth, can we make yum not to abort when it sees an unsigned package?
Or at the very least it would be a huge improvement if it printed ALL
unsigned packages before quitting, and not just the first one.
