## Conf

Base conf:

  - [videobridge.conf](https://github.com/jitsi/jitsi-videobridge/blob/master/jvb/src/main/resources/reference.conf)
  - [jicofo.conf](https://github.com/jitsi/jicofo/blob/master/src/main/resources/reference.conf)

the following is used in videobridge.conf:
[jicoco/MucClientConfiguration](https://github.com/jitsi/jicoco/blob/master/jicoco/src/main/java/org/jitsi/xmpp/mucclient/MucClientConfiguration.java)

How the new configuration is read in jicoco:
https://github.com/jitsi/jicoco/blob/master/jicoco-config/src/main/kotlin/org/jitsi/config/JitsiConfig.kt#L83-L91
They use this library: https://github.com/lightbend/config
We are particularly interested by: https://github.com/lightbend/config#standard-behavior
Using 'application.conf' with classpath does not seem to work.
But, specifying the file path as `-Dconfig.file=/etc/jitsi/jicofo.conf` works!
