The first question to ask yourself is whether you want the rpm to start the service. If the rpm will only ever be installed from CDROM, you don't want to start the service. If the rpm might be installed from CDROM, you won't want to start the service duing CDROM install, but you might want to at other times. You'll need to work out how to detect whether the installer is running, or the system is up and fully running. If the rpm will be installed by a higher level management system (some equivalent of Mitel blades), then service control might be provided by that system (so that you can ensure that all rpms are installed and configured before you try to start services). OK, now you want to start the service. If the service directory does not contain a 'down' file, there's nothing to do - svscan will find the service directory and start the service for you. If the service directory does contain a 'down' file (which it would if you wanted to delay startup of the service during bootup), then you would wish to start it, which you can do with any of: /etc/rc.d/init.d/xxxx /etc/rc7.d/Snnxxxx svc -u /service/xxxx Of these, only /etc/rc7.d/Snnxxxx will check the config database for a "status == enabled" property for the service. If you care about the db property, that's what you'll want to do. Whichever way you do it, "svc -u" will eventually be called, and is what will actually bring the service up. -- Charlie Brady [EMAIL PROTECTED] Mitel Networks Corporation http://www.mitel.com/ Phone: +1 (613) 592 5660 or 592 2122 Fax: +1 (613) 592 1175 A: Because we read from top to bottom, left to right.
