Ok, i only tried "upgrade" once manually to get another box from centos4.4 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.
No. And it wouldn't help you. There is no such thing as an "upgrade" in reality. An "upgrade" to 4.7 is just an update to the bunch of rpms that is considered to be "4.7". e.g. *any* update of dhcrelay might create the problem you saw.
Regarding "update" versus "upgrade", I'd like to give reference to this forum thread:
http://www.centos.org/modules/newbb/viewtopic.php?viewmode=flat&topic_id...
It boils down to Seth Vidal's own words,
"upgrade/update do the same thing unless you've gone out of your way to disable obsoletes in your yum.conf"
and who else can say more about yum than Mr. Vidal? :-D
