1. You have to create a user with uid 250: mumble-server
2. And a group with gid 250: mumble-server
3. And create the DIRECTORIES  /var/log/mumble-server 
   /var/lib/mumble-server /var/run/mumble-server owned by mumble-server user and group
4. Configure murmur.ini config file: /etc/murmur.ini
   Change the variables with 
   Database=/var/lib/mumble-server/mumble-server.sqlite
   pidfile=/var/run/mumble-server/mumble-server.pid
   logfile=/var/log/mumble-server/mumble-server.log
   uname=mumble-server
   
   NOTE: Step 1-3 can easily be done by 'sh config-helper.sh' in current
   directory.
   
   Have fun :-)
