The safe and obvious thing to do is to place dependencies on all services you actually depend on. (With comments in the XML is best, so that future maintainers don't have to guess at why.) As you mention, then you're resilient to changes in your dependency's dependencies. ;) > also, i'm assuming that if i have more than one <dependency> that > "AND semantics" are used: eg, my Svc starts when "sysevent AND Minimal" > is True. is my assumption correct ? Yes. A service is not started until all of its dependencies are satisfied. (For require_all dependencies, that maps to the statement you made above.) liane
