Package: lvm2 Version: 2.02.176-1 Severity: normal I don't know whether the bug here lies in dh_installsystemd or in lvm2, so please reassign to dh_installsystemd if this is the wrong package.
At the end of lvm2's debian/rules, it says: dh_installsystemd --remaining-packages But the lvm2 postinst then ends up finishing with the following: # Automatically added by dh_installsystemd/10.10.5 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 >/dev/null || true fi # End automatically added section and this throws up the warning message: Syntax: /usr/bin/deb-systemd-invoke <action> <unit file> [<unit file> ...] because no unit file is listed after $_dh_action. I'm inclined to think that this is a debhelper bug...
