+Well, sort of.  It's not an issue of efficiency, but of convenience and
+just making it possible to do without resorting to manual use of the rpm
+command. 
+
+The rpm command "knows" that a new version replacing the old version
+supplies the same things that the old one did, so it will quietly allow
+the upgrade.  It will also do what we need, i.e. go the other way and
+replace a newer version with an older one if you use the --oldpackage
+keyword.  We just need urpmi to support its use.
