On a newer 6.13 package, the --no-enable and --no-start flags are gone, so postinst gets a new block: # Automatically added by dh_installsystemd/13.11.4 if [ "$1" = "configure" ] || [ "$1" = "abort-upgrade" ] || [ "$1" = "abort-deconfigure" ] || [ "$1" = "abort-remove" ] ; then if [ -z "${DPKG_ROOT:-}" ] && [ -d /run/systemd/system ]; then systemctl --system daemon-reload >/dev/null || true deb-systemd-invoke start 'system-xfs_healer.slice' 'system-xfs_scrub.slice' 'xfs_scrub_all.timer' >/dev/null || true fi fi which actually starts it. But this shouldn't have been started up on your system. <confused> --D > Thanks, > > David. >
