Note that you need to start (i.e. enable) the service first for this to work. In systemd only stuff that is started gets stopped... I presume "wait_borg" talks to some other service "borg" waiting for it to complet what it is doing? Note that with the above you are not ordering the main "borg" service against your wait service, which means the "borg" service might get stopped in parallel with your wait service. You probably want a "After=borg.service" or so in the [Service] section of your wait service (this is because the shutdown order of services is always the reverse of the start-up order of services in systemd, and with After=borg.service you hence say that your service shall be terminated first, and borg.service shall be terminated only after it finished.

Inhibitors (currently) only block if the request comes from an unprivileged user. I guess the reason behind that is, that you could circumvent that anyway, if you are root. See https://github.com/systemd/systemd/issues/2680 Personally I would find it useful if systemd-inhibit would have a switch to also respect inhibitors for root. -- Why is it that all of the instruments seeking intelligent life in the universe are pointed away from Earth? ___ systemd-devel mailing list systemd-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/systemd-devel

Well, it does wait when I press the power button on the case. It does not wait if I enter as root poweroff or reboot.

Hi Michael, this solution has a couple of drawbacks: - block will let shutdown, etc. fail, I do only need a pause/wait - delay does not work with reboot Regards, Ralf Gesendet: Sonntag, 02.

[systemd-devel] blocking service on shutdown
Hi, I want my system to pause on shutdown to wait till my backup has finished if it is running. For this I've created this small service: [Unit] Description=borg shutdown wait [Service] Type=oneshot ExecStart=/bin/true RemainAfterExit=true ExecStop=/usr/local/bin/wait_borg TimeoutStopSec=600 [Install] WantedBy=multi-user.target I'm using ubuntu 18.04, systemd 237 Manually stopping the service via systemctl stop borg_wrapper does wait and thus works. But its not working on normal shutdown/poweroff ... From the logs I can't even see an entry with "Stopping borg shutdown wait" in syslog. Does anyone has an idea?
