/* omjournal.c
* send messages to the Linux Journal. This is meant to be used
* in cases where journal serves as the whole system log database.
* Note that we may get into a loop if journald re-injects messages
* into the syslog stream and we read that via imuxsock. Thus there
* is an option in imuxsock to ignore messages from ourselves
* (actually from our pid). So there are some module-interdependencies.
