I suppose if that were the proper place to put it, the command would be
listed in the man pages for syslog.conf

of course it's not the correct place to put the '-r', the proper place
is in the command used to launch syslogd which would generally be the
sysconfig for syslogd but on a RH 7.3, that may not exist and you might
have to insert it into /etc/init.d/ - I don't know, I've long since
retired all my RH 7.x systems

no
