It seems there are some inconsistencies about daemon logging on Snow Leopard:

- asl(3) logs to the log database and system.log

- NSLog logs only to system.log

- printf logs nowhere

The documentation states that NSLog uses asl(3), however these logs do not appear in the log database.

Also the "Daemons and Agents" tech note states:

Logging With printf
In Mac OS X 10.5 and later, launchd will capture any output to stdout and stderr and redirect it to ASL.

However I fail to see any printf reaching the log database or even system.log.

Why is that?

Thanks,

Thomas
