I wouldn't expect that based on the traditional custom of syslog daemons. If you specify a filter configuration, such as setlogmask or some custom logic in the syslog daemon itself, the logging system should respect it. Even if it might not make sense to a given individual.

That said, rte_panic should be making sure the messages it generates always get logged, regardless of the logging system settings, because it is hijacking control of your process which is a very hostile act. This special exemption should only happen for things that are truly fatal. Not anything else.
