 set to 0 to launch the respective daemons.
 
+The ovs section section also supports the options below, to configure a set of
+SSL CA, certificate and private key. After adding these to Open vSwitch, you
+may specify ssl: connection methods for e.g. the OpenFlow controller. Note that
+Open vSwitch only reads these files during startup, so it needs to be restarted
