I have previously used FC6/FC7 and I think it is different.   Cannot
remember.   But now all my FC10 are like what u said above:

/etc>ps auxwf|grep syslog
root      2577  0.0  0.0 114012  1860 ?        Sl   07:20   0:00 rsyslogd -c 3

/etc>cat /etc/rsyslog.conf
# Log all kernel messages to the console.
# Logging much else clutters up the screen.
#kern.*                                                 /dev/console

# Log anything (except mail) of level info or higher.
# Don't log private authentication messages!
*.info;mail.none;authpriv.none;cron.none                /var/log/messages

So if u remarked the above out, nothing will go into
/var/log/messages, whcih is what I normally do to improve performance
(after I had instrumented a lot of the kernel codes) - as the I/O does
slowed the system a lot.
