Note that this version of syslogd/klogd ignores /etc/syslog.conf.
Options:
-m Change the mark timestamp interval. default=20min. 0=off
-n Do not fork into the background (for when run by init)
-K Do not start up the klogd process (by default syslogd spawns klogd).
-O Specify an alternate log file. default=/var/log/messages
-m NUM Interval between MARK lines (default=20min, 0=off)
-n Run as a foreground process
-K Do not start up the klogd process
-O FILE Use an alternate log file (default=/var/log/messages)
