Description=SmartBotic Runner Service
Documentation=https://github.com/smartbotic/smartbotic
# Ordering only, deliberately not a Requires. The runner is built to survive
# the webserver being absent - it retries node sync on reconnect_interval_ms
# and re-registers on its heartbeat - so a hard requirement bought nothing even
# when both ran on one host. It actively breaks a split deployment: with the
# webserver on another machine the unit does not exist locally, and the runner
# then refuses to start at all with "Unit smartbotic-webserver.service not
# found". After= on a missing unit is simply ignored, which is what we want.
After=network.target smartbotic-webserver.service

# Without PartOf, "systemctl restart smartbotic.target" starts nothing and
# stops nothing: a target is only a grouping, and restart/stop do not reach
# its members through Wants alone. That silently leaves an old binary running
# after a rebuild, with systemctl still reporting the target as active.
