  This is a frustrating game of whack-a-mole.  Person A comes up with a
position, I rebut it, and then person B comes up with a different
position, and I have to rebut it..  There have been people in this
thread who have said that the program best knows what it needs, and
should handle its own initialization.  That was what I was replying to.
I'll reply to your position now.

  So instead of the initscript doing the checking+setup and launching
the service, it launches a a second script... which does the
checking+setup and launches the service <FACEPALM>.  See my post with
the joke of digging a second hole to dump the dirt from the first hole
into.  Instead of one script, we now have two scripts.  This is *NOT*
simplification.

  I don't understand what you're arguing here.  *THE INITSCRIPT IS OWNED
BY THE SERVICE PACKAGE*, not by the init package.  E.g. net-misc/openssh,
not sys-apps/openrc.

  That's the way it is right now.  See above.

  My point in this whole argument is that there is some checking and
setup that has to be done before launch.  Therefore shuffling off some
or all of the shellscript code to another script is a pointless "shell
game" (sorry) that adds no value.
