It was the mirror having not sync'd up all the updates.
I did notice something, that might have been true before, but just noticed now. The kernel development headers are marked as upgrades to the previous ones so you can only have one installed at a time.
That makes it hard to compile kernel drivers for previous versions you may have installed if you need to revert back to the previous version.
That is true, and is how the version of YUM is written that is included in c4 ... you can fix this issue with this line in your yum.config file (all one line):
installonlypkgs=kernel kernel-smp kernel-devel kernel-smp-devel kernel-largesmp kernel-devel-largesmp kernel-hugemem kernel-hugemem-devel
Thanks, mate, that should help.
So the above option will make sure that the kernel-devel* are included in the installonly algorithm.
Is there an option to select how many previous installonlys are to be allowed? I looked in the man pages, but didn't see the option there. I just want to bump it to 3 from 2.
I believe there is an installonlyn plugin you could probably get.
