FC3 to FC4 upgrade problems

[Peter J. Stieber]

I have a dual opteron box and I believe I had every possible FC3 package 
loaded on it. I created a FC4 install DVD and attempted to upgrade using 
anaconda. The installation seemed to complete after an hour and 45 min. 
When the machine rebooted, it booted the same FC3 kernel I was using 
before the install and there were no FC4 kernels installed on the 
machine.

For some reason I do not understand, very few of the packages were 
upgraded to FC4. I used rpm -qa | grep -i fc4 and less than 20 packages 
were FC4. rpm -qa | grep -i fc3 on the other hand listed tons of 
packages.

BTW The /etc/fedora-release was updated to FC4, but "yum update" had 
problems with package dependencies and refused to update.

Is there a package dependency problem floating around?

How can I upgrade my system to FC4.

Pete

PS: Does the FC4 installation dvd do anything other than this:
1) Update /etc/fedora-release with an FC4 string
2) execute "yum update"
when updating?
