Sometimes our logs get very large, usually due to bugs or because the user is running UMS in TRACE log mode for debugging. It would be useful to split the logs at an interval (maybe every 100MB) to make it easier to open them in editors

The instructions for docker-compose reference a volume called gerbera-config, but it is not declared, so starting the container fails with

ERROR: Named volume "gerbera-config:/var/run/gerbera:rw" is used in service "gerbera" but no declaration was found in the volumes section.

The container needs to be declared with

volumes:
  gerbera-config: {}

However, I don't thin

It would be good to set it by hash(machine-id, ip, port) or something similar
