Right, but the configuration is not using the syslog protocol.  It's using
LocalSyslogAppender, which is supposed to be calling the C syslog()
function, and it's supposed to use LOG_DAEMON, which uses the facility
shifted by 3 (because it's combined with the priority).

I think I need to go look at the source code again.
