[opensuse-security] Automatic update silently broken after removing zmd-updater, zen, and rug (OpenSUSE 10.2)

Hello everyone. Automatic weekly updates stopped working after I did a rpm -e zmd-updater zen rug for OpenSUSE 10.2 machines. If this is my fault, configuring (again) automatic update in yast should warn me that automatic updates will not work. Greetings Sven
