When you do a chkconfig servicename on it will take the first number (30, in your example) and create the symbolic linknames of S30servicename. When you do a chkconfig servicename off it will delete the S symbolic linknames and create the K20servicename link. These are established in the rc?.d/ directories. chkconfig will do it to rc[2-5].d/ unless you specify --level as an option which will restrict the rc?.d/ directories it manipulates. Ultimately the /etc/rc.d/rc script is the one responsible for doing this and executes the scripts one at a time in alphabetical order. Since the start scripts are of the form Snnservicename, even if two services have the same number, it will then do them in "servicename" alphabetical order. HTH, --Rob
