+- Be sure to update /etc/conf.d/wsdd!  
+- If using single instance all fields of /etc/conf.d/wsdd should be commented out!  
+- If using multiple instances (wsdd.INSTANCE...) be sure to set all fields in /etc/conf.d/wsdd in ALL instances!  
+- UUIDs can be generated with `uuidgen -N test.mh3000.net -n @dns -s`
