# We want systemd to give guest-client some time to finish gracefully, but
# still want it to kill guest-client after TimeoutStopSec if something went
# wrong during the graceful stop. Normally, systemd sends SIGTERM signal right
# after the ExecStop, which would kill heartbeat. We are sending useless SIGCONT
# here to give guest-client time to finish.
KillSignal=SIGCONT
# Exit code of 6 indicates it is not configured and no restart.

# if it is not configured.
