kernel-devel should be installed alongside, not upgraded. So if you have

kernel-a
kernel-devel-a

installed and do a yum update, you should end up with

kernel-a
kernel-b
kernel-devel-a
kernel-devel-b

installed on your machine, for example if you have to go back one kernel
 as a module you need doesn't compile on kernel-b. If you didn't have
kernel-devel-a anymore at that point, that could get quite ugly.

I am against changing the kernel spec file. To clear up what Fedora did
with their kernels: Have each kernel-devel package (kernel-devel,
kernel-smp-devel, kernel-xen0-devel) also Provide: kernel-devel. This
way yum sorts out that all kernel-*-devel need to be installed instead
of upgraded.

Bad idea (even if you mean installonlypkg here). It's no consistent
behaviour, if kernel-devel gets installed and all other kernel-*-devel
packages get updated.

By the way: If we change yum according to 1), people using the
installonlyn plugin will get the kernel-*-devel package removed, when
the corresponding kernel package gets removed by the package.

Hehe.
