While this usually isn't a problem for the updates repo (though there 
have been times where kernels were not usable by me for several months 
even in the released branches), it's not so nice for rawhide (possibly 
plus the rawhide nodebug repo) where there can be new kernels pushed 
to rawhide each day (and more than one if you're testing things from 
koji).

For example right now I need to use a 3.15 kernel on one of my machines 
because of an issue affecting md raid and the running kernel is the oldest 
and only working kernel installed on that machine. And on another machine, 
I think I have a Nouveau regression (I'm not sure yet and haven't had time 
to diagnose that problem) and again I need to use a 3.15 kernel which is 
both the running kernel and the oldest installed kernel.
