[Letsencrypt-devel] Bug#849800: debhelper: dh_systemd_start --no-start has no effect

[Peter Colberg]

Package: debhelper
Version: 10.2.2
Severity: normal

Dear Maintainer,

I would like to add a systemd service and timer to acmetool that is
to be explicitly enabled by the user. debian/rules looks as follows:

~~~
override_dh_systemd_enable:
        dh_systemd_enable --no-enable acmetool.timer

override_dh_systemd_start:
        dh_systemd_start --no-start acmetool.timer

override_dh_installinit:
~~~

However, first-time installation of the package yields this warning:

~~~
# dpkg -i acmetool_0.0.58-5_amd64.deb
Selecting previously unselected package acmetool.
(Reading database ... 52232 files and directories currently installed.)
Preparing to unpack .../acmetool_0.0.58-5_amd64.deb ...
Unpacking acmetool (0.0.58-5) ...
Setting up acmetool (0.0.58-5) ...
acmetool.timer is a disabled or a static unit, not starting it.
~~~

Inspecting the generated postinst it appears --no-start is ignored:

~~~
# Automatically added by dh_systemd_start
if [ -d /run/systemd/system ]; then
        systemctl --system daemon-reload >/dev/null || true
        if [ -n "$2" ]; then
                _dh_action=try-restart
        else
                _dh_action=start
        fi
        deb-systemd-invoke $_dh_action acmetool.timer >/dev/null || true
fi
# End automatically added section
~~~

Should the above snippet not be omitted with --no-start?

Regards,
Peter
