I have a oneshot .service (certbot) that is run by its .timer with: OnCalendar=daily RandomizedDelaySec=1day
I also have a sometimes long-running script that may modify the same data. So the script and the oneshot service should never run at the same time. Is there a good systemd pattern for some kind of semaphore-like thing that will delay the execution of the oneshot service and try again when the script is done running? I could skip execution, but then I miss an entire day until the service is run again -- I’d prefer it if it tried again a few minutes later. Or I could poll for some flag before running the main part of the service. Wondering whether there something more systemd-native. Thanks, Johannes. _______________________________________________ systemd-devel mailing list systemd-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/systemd-devel
