Agreed. I just set the compat to 10, updated the cowbuilder base, removed
the build-depends on dh-systemd, and removed the --with systemd option for
dh. It built okay.

There is one point that might be useful - either in the package or in a
wiki.

When using tiny rules:

%:
    dh $@

and the package contains a systemd unit file, but no sysv init file,
lintian complains:

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

and there is unnecessary cruft in the pre/post scripts.

When I add:

override_dh_installinit:
        dh_installinit --no-scripts

to debian/rules

I get a clean lintian and the pre/post scripts don't reference nonexistent
init scripts.

I don't know the best place to document this idea of telling debhelper to
not bother with the init script if it doesn't exist.

Perhaps I should file a bug against debhelper.

Thanks!
