While Forti and its IPSEC is still in the works, I've posted short tutorial on how to get delayed hibernation working on every GNU/#Linux + SystemD based distro. https://sirmacik.net/delayed-hibernation-on-linux-with-systemd/?lang=en
@tadzik what's your distro? Tbh it's possible it might not be there. Part with cp was written from memory.
@tadzik run systemctl status suspend.service
@tadzik ino, it still isn't :/ Additionally debian/ubuntu tend to add their own changes like changing default paths for NetworkManager plugins and so on.
@tadzik and thanks, I've updated the post (:
@tadzik additionally:
~ % locate suspend.service
/etc/systemd/system/systemd-suspend.service
/usr/lib/systemd/system/systemd-suspend.service
/usr/share/man/man8/systemd-suspend.service.8.gz
