Aha.  I believe that is fixed in compat 11 (still WIP though).  In
compat 11, dh_installinit will ignore systemd files and accordingly not
assume it should do something.

I have added a remark in the dh_installinit manpage about it might make
sense to skip dh_installinit for packages in compat 10 and earlier, when
they only skip systemd services and no sysvinit scripts.


The actual text being (review welcome):

"""
In compat 10 or earlier: If a package only ships a systemd service
file and no sysvinit script is provided, you may want to exclude the
call to dh_installinit for that package (e.g. via B<-N>).  Otherwise,
you may get warnings from lintian about init.d scripts not being
included in the package.

You already did. ;)  When dh-systemd was merged into debhelper, all of
its outstanding bugs got reassigned to debhelper.

Thanks,
