But this is the whole difference between them. An init.d script
*shouldn't* do all that. It *knows* how the system daemon is
configured and should only be used to start and stop that process. And
it can't wait, it's not an interactive tool, it has to implement the
standard init.d interface.
An interactive tool can dwim automatically but that isn't appropriate
for a startup script. A startupt script should always do the same
thing exactly and do that based on the OS policy, not based on
inspecting what programs are actually running on the machine.
