I guess the complication arises from the fact that<br>
dh_installinit/invoke-rc.d directly handles systemd service files if the<br>
SysV init script and service file name match.<br>
dh_installsystemd only handles those unit files for which no<br>
corresponding SysV init script exists.<br>
<br>
I think the solutions for this could be, to let dh_installsystemd handle<br>
all systemd unit files.<br>
dh_installinit/invoke-rc.d on the other hand would be updated to only<br>
handle SysV init scripts.<br>
<br>
In the long run I guess this will be less confusing at is clearer which<br>
tool is responsible for which task and it makes it easier to override<br>
the behaviour in debian/rules.<br>
<br>
Felipe has been doing some initial work for enable that kind of<br>
behaviour at<br>
