Bug 158148

Description of problem:

Yum is configured to exclude kernel updates and several other RPMS on some of my
FC3 systems because I am using LVM on DMCrypt and require a custom ramdisk to
boot.  Yum upgrade of the kernel without supervision makes my systems unbootable.

The exclusion normally works, but if another package appears in updates that I
am not excluding which contains a claimed dependency on a newer kernel, the
kernel gets picked up to satisfy the dependency. 

Version-Release number of selected component (if applicable):

yum-2.2.0-0.fc3

How reproducible:

It happens every time something depends on a newer kernel.

Steps to Reproduce:
1.set yum to exclude=kernel*
2.run regular updates until something depends on a newer kernel.
3.recieve new kernel inspite of configuration 
  
Actual results:

New kernel is installed

Expected results:

New kernel is not installed, or possibly yum update fails due to dependencies
that can not be met.

I would be glad to perform whatever tests are needed.
