The following reply was made to PR docs/30374; it has been noted by GNATS.

Is't impossible to generate a LOG_KERN using syslog(3). Only kernel can generate these. LOG_KERN | LOG_NOTICE == LOG_NOTICE, as LOG_KERN is defined as (0<<3). And libc/gen/syslog.c defaults facility to LOG_USER: : static int LogFacility = LOG_USER; /* default facility code */ [...] : /* Set default facility if none specified. */ : if ((pri & LOG_FACMASK) == 0) : pri |= LogFacility; LOG_KERN is defined as follows: #define LOG_KERN (0<<3) /* kernel messages */ #define LOG_USER (1<<3) /* random user-level messages */ So if you call ``logger -p kern.notice'', that becomes as if it were ``logger -p user.notice''. This is also documented in the syslog(3) manpage: : LOG_KERN Messages generated by the kernel. These cannot be : generated by any user processes. [...] : LOG_USER Messages generated by random user processes. This : is the default facility identifier if none is specified.
