Is there some way we could get the initrd rebuild to be more verbose, so that it doesn't appear to hang? It would be nice to get feedback that something is happening, especially on an older, slower system that takes a long time for this step. I run into the same problem with the kernel-devel package, just because of the sheer number of files involved. I've learned to be patient and expect a kernel upgrade on my oldest system to take a very long time. (I need the -devel package to rebuild an ancient 3rd party driver no longer provided by RHEL.)
