[syslog-ng]Where to put in startup scripts?

Hi everyone! Got a nice working installation of syslog-ng in our computers. But I have aquestion about the startup script. We are running a mixed environment with RedHat Linux and IRIX, and for now we have the startupscript for syslog-ng located at S99, ie we start it last of all services. Now where should we start it? Is there any recommendations? BR
