 The openHAB2 user interface "Paper UI" writes to /var/db/openhab2
 (config) and to %%ETCDIR%% (when installing add-onds).
 The config in %%ETCDIR%% is evaluated additionally to
 /var/db/openhab2.
 
 See %%PREFIX%%/etc/rc.d/openhab2 for environment variables you need
 to set by hand (all "export"-ones) if you want to execute some of
 the openHAB2 commands from the shell directly.
 
 When the openHAB2 docs talk about "userdata", look into /var/db/openhab2.

+Serial ports do not work with FreeBSD, see:
+	https://github.com/openhab/openhab1-addons/wiki/FreeBSD
+
+By default openHAB2 tries to use IPv6. As FreeBSD does not support
+mapping IPV4 multicast addresses inside IPv6 addresses you will get
+the following error message:
+	[ERROR] [org.jupnp.transport.Router] - Unable to initialize network router: org.jupnp.transport.spi.InitializationException: Could not initialize MulticastReceiverImpl: java.net.SocketException: Invalid argument
+
+A workaround is to use the following rc.conf setting which will
+prefer IPv4 over IPv6:
+	openhab2_java_opts="-Djava.net.preferIPv4Stack=true"
