systemd service unit causing lintian init issues

[Matt Zagrabelny <mzagrabe@d.umn.edu>]

Greetings,

I'm packaging up a firewall script that ships with a systemd service
unit file. lintian is complaining about an init script:

% lintian fw-skel_0.06-1_all.deb
W: fw-skel: init.d-script-not-marked-as-conffile etc/init.d/fw-skel
E: fw-skel: init.d-script-not-included-in-package etc/init.d/fw-skel
%

There is, of course, no init script:

% dpkg-deb -c fw-skel_0.06-1_all.deb  | grep init
%

The postinst and prerm both reference an absent init script:

% dpkg-deb -e fw-skel_0.06-1_all.deb
% grep init DEBIAN/*
DEBIAN/postinst:# Automatically added by dh_installinit
DEBIAN/postinst:if [ -x "/etc/init.d/fw-skel" ]; then
DEBIAN/postrm:# Automatically added by dh_installinit
DEBIAN/prerm:# Automatically added by dh_installinit
DEBIAN/prerm:if [ -x "/etc/init.d/fw-skel" ]; then
%

It seems that dh-systemd is working in some capacity:

% dpkg-deb -c fw-skel_0.06-1_all.deb| grep systemd
drwxr-xr-x root/root         0 2015-09-23 15:18 ./lib/systemd/
drwxr-xr-x root/root         0 2015-09-23 15:18 ./lib/systemd/system/
-rw-r--r-- root/root       200 2015-09-23 15:18
./lib/systemd/system/fw-skel.service
%

I'm building this using a sid cowbuilder + gbp, FWIW.

Any ideas for keeping SysV init out of the postinst and friends?

Thanks!
