This package includes a system-wide installation of murmurd. If you want a personal server running on your own user account, use the murmur-user-wrapper script. Murmur's root user is called SuperUser. To set the password for superuser, simply dpkg-reconfigure mumble-server. The mumble-server init script is silent concering messages to the console on startup/shutdown by default; if you wish to see start/stop messages to the console on upgrades, uncomment "VERBOSE=yes" in /etc/default/rcS.
