Hello,
the log_custom does not implement any syslog-kind-of-protocol, it simply
sends out the plain log message to a remote target, it does not rely on
LOG_LOCAL0 at all.
During startup, till the config is parsed and modules initialized,
various logs can go to the local system, not being handled by log_custom.
Cheers,
Daniel
