With rpm one cannot stop learning :) Indeed, if all shared libs were already packaged in the suggested scheme, this would catch them all. I don't think everything should be packaged that way (distribution invariants like glibc for instance not), and such a idiom would also need its time to spread into rawhide, so having the Provides: shared-library-package is a good hook to distinguish leaf-disposable packages from others that are bundling libs and further stuff. -- Axel.Thimm at ATrpms.net
