AW: [CentOS] Nightly yum update did an "upgrade"

Ok, i only tried "upgrade" once manually to get another box from centos4.4 to a 4.5 ( and I ran into this ) 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.
