Normally the daemon must be run with root-privileges. Nevertheless it is
possible for a normal user to start the daemon as long as
the configuration file exists and is empty, as in this case no mount()
calls are issued (which is the only thing that actually requires root
status).
In this case the daemon must be compiled without the
MONITOR_MOUNT_COUNT option. Otherwise it will block at the
beginning of the main loop as there are no mountable devices.
