Jvb muc_nickname

I have setup with 4 Jitsi servers:

  1. Main server for Prosody, Jicofo and NGINX
  2. Videobridge2
  3. Videobridge2
  4. Videobridge2

I want to somehow dynamicaly set org.jitsi.videobridge.xmpp.user.shard-1.MUC_NICKNAME=jvb is that possible?
Environment variable? Automatically generated UUID if not present?

Right now I will patch this by using /etc/rc.local script to generate this config…

I want to be able to just start videobridge machines, so they can easily join the cluster.
