The lldpad or corosync package ship a native systemd unit. Looking at the generated postinst: > # Automatically added by dh_installinit/11.2.1 > if [ "$1" = "configure" ] || [ "$1" = "abort-upgrade" ] || [ "$1" = > "abort-deconfigure" ] || [ "$1" = "abort-remove" ] ; then > if [ -x "/etc/init.d/corosync" ]; then > update-rc.d corosync defaults >/dev/null > if [ -n "$2" ]; then > _dh_action=restart > else > _dh_action=start > fi > invoke-rc.d corosync $_dh_action || exit 1 > fi > fi > # End automatically added section > # Automatically added by dh_installsystemd/11.2.1 > if [ "$1" = "configure" ] || [ "$1" = "abort-upgrade" ] || [ "$1" = > "abort-deconfigure" ] || [ "$1" = "abort-remove" ] ; then > # This will only remove masks created by d-s-h on package removal. > deb-systemd-helper unmask 'corosync.service' >/dev/null || true > > # was-enabled defaults to true, so new installations run enable. > if deb-systemd-helper --quiet was-enabled 'corosync.service'; then > # Enables the unit on first installation, creates new > # symlinks on upgrades if the unit file has changed. > deb-systemd-helper enable 'corosync.service' >/dev/null || true > else > # Update the statefile to add new symlinks (if any), which need > to be > # cleaned up on purge. Also remove old symlinks. > deb-systemd-helper update-state 'corosync.service' >/dev/null > || true > fi > fi > # End automatically added section The problem is, that dh_installsystemd enables the service *after* a start attempt has been made and systemctl is-enabled checks for the state of the native service unit. With dh_systemd_enable/start, the enable part was before the start. It's a bit like https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=887904 The old code worked, as it checked the status of the SysV init script, not the enabled state of the native service file. -- Why is it that all of the instruments seeking intelligent life in the universe are pointed away from Earth?
