/sbin/busybox should be statically linked, not dynamically linked. From the source rpm, it looks like the file busybox-static.patch contains the wrong thing. I looked at the srpm for busybox-0.51.xxx and it contains what looks like the proper patch file for static linking. This breaks anything boot/rescue disk which is relying on busybox not needing other libraries.
