I have no moustache. ;-) But otherwise you are right.

Let me say here that the scripts in /etc/init.d resp. everything run via
/sbin/service already will have the necessary glue code in there as soon
as Bill merges https://bugzilla.redhat.com/show_bug.cgi?id=612728 . It
will forward start/stop requests to systemctl. That means people can
continue to use "/etc/init.d/foo start" and "/sbin/service foo start", and
the right thing will happen and they'll learn something too.

We can add similar code to chkconfig too: something that warns the admin
when a native systemd unit file exists, and then redirects the command
properly. It is now on my todo list, but not even near the top of the
list.

I would greatly appreciate if somebody would work on this, because I am
currently pushing this through single-handedly everywhere else now. In
fact I'd appreciate help in all areas. For example, if somebody would
pick up the /var/run resp. /var/lock on tmpfs issue I'd be a happy
man. Or if somebody would help me and post the unit files from
http://0pointer.de/public/systemd-units/ on bugzilla, then I'd be even
happier.

Of course, if the other folks on this list think that bike-shedding and
nitpicking is time better spent then actually doing things and helping
with the integration, then they are welcome to continue wasting my time
by wanting to discuss the names of the binaries we use. Jeez.
