System policy dictating governor over the ugliness we do in the cpuspeed init script would be nice. Even nicer would be if we could outright get rid of the initscript (not sure what people who need the cpuspeed daemon are to do in that case though). -- Jarod Wilson jwilson@xxxxxxxxxx -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
