While zypper dup from openSUSE 13.1 to 13.2 I've seen:

( 878/3412) Installation von: wicked-service-0.6.12-1.1
......................................................................................................[fertig]
Zus�tzliche rpm-Ausgabe:
Network is managed by NetworkManager.service
 and rcnetwork does not support '' action.
scripts/functions.common: line 138: logger: command not found
Use systemctl for systemd specific actions.
scripts/functions.common: line 138: logger: command not found


I guess that's caused by a missing prereq statement in the wicked-service
package.
