Ok, i only tried "upgrade" once manually to get another box from centos 4..4 to a 4.5 ( and I ran into this http://bugs.centos.org/view.php?id=2557 ) and thought, the difference between update and upgrade is like the debian based "apt-get upgrade" and "apt-get dist-upgrade".
The man page states this as well, vandaman is right, I should have RTFM, but I was a bit in a hurry and I thought, I could get some quick help here.
That bug is unreproducible because you have manually altered the yum configuration so in reality its a self-induced problem not a "bug". If you are new to using a mailing list follow some of these guidelines :- http://lists.centos.org/pipermail/centos/2008-October/065626.html
