This way they can cleanly exit (with a SIGTERM or systemctl stop) but will get restarted if killed or they abort, but only for StartLimitIntervalSec= time period with a total maximal count of StartLimitBurst= retries. See `man systemd.unit` for details, default are 10s total restart retry period with at max 5 total retry counts, after that the unit will placed in the failure state. So this is a best effort try with no real downside. Signed-off-by: Thomas Lamprecht <t.lamprecht@proxmox.com>
