Re: [SR-Users] log_facility is not always 'LOCAL0' when loadmodule log_custom.so

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
