+Shouldn't those packages also rely on the new RPM check? Or you mean
+just update those packages and don't allow for symlinks between /bin and
+/usr/bin (+same for sbin)?
+
+Would the new RPM do a runtime check to see if things have been
+migrated?
+
+Does Dracut usrmove handle the packages which at the moment contain
+symlinks (e.g. /bin/foo -> /usr/bin/foo and e.g. /usr/bin/bar ->
+/bin/bar)? Or should either dracut or the packages have conflicts to
+deal with this?
