_syslogd_ *explicitly* does -not- _create_ any log files. it is documented
in the manpages that it behaves that way. Whether or not this is a "good
idea" is debatable, but it does allow you to suppress some logging w/o having
to edit the syslog.conf file and/or re-start syslogd.

Syslog does -not- give any such messages, it just doesn't write the message
anywere.
