You sound like you're looking to do deeper integration with OpenSolaris, if you're talking about changing the mounting order of filesystems. In general, no, you shouldn't just call other startup scripts on the system. Instead, you should create a service which depends on the things you require. Then you can make other services depend on your services by using "dependents". If you can't do that because your service depends on something that starts "too late", you'll need to work with the folks who own the service you need earlier. In general, people haven't made core OS services start late for no good reason -- they start where they start because they depend on other services. Making them start earlier will break certain configurations of the OS that you might not have considered yet. >> >> PS: If this is not the right list. please guide me to one! >> I felt this was the closest mailing list. >> >> > > rc scripts are a thing of the past in OpenSolaris. Just a bit of clarification. rc scripts are still supported for compatibility purposes (e.g. ISV software, or administrator-created scripts). But as Jeff said, OpenSolaris software should deliver SMF services, not rc scripts. > You should check out > the smf(5) faq <http://opensolaris.org/os/community/smf/faq/> and the > Service Management Facility community > <http://opensolaris.org/os/community/smf/>.
