The kernel package runs hardlink on /lib/modules/*/build/ in %post to save 
space on FC2 and FC3, that's what's taking so long when installing and 
removing kernels. That's no longer the case on devel tree kernels where 
the headers have been split out to separate kernel-devel package for those 
who need it. Kernel-devel still does the hardlink, but that doesn't 
affect nearly as many people.
