This means if you add the swap only after the hibernation was already initiated then this will not be able to affect the check anymore. You can bypass this check by setting the SYSTEMD_BYPASS_HIBERNATION_MEMORY_CHECK env var for the logind service (add a drop-in using Environment= for it).

[systemd-devel] enable/disable swap before/after hibernation
Dear list, I want to enable/disable the swap partition before/after hibernation. However, it seems I cannot get the service to run early enough to avoid the error: Failed to hibernate system via logind: Sleep verb not supported The .service file looks as follows: [Unit] Description=… StopWhenUnneeded=true Before=hibernate.target [Service] Type=oneshot RemainAfterExit=yes ExecStart=/sbin/swapon /my/device ExecStop=/sbin/swapoff /my/device [Install] RequiredBy=hibernate.target The service file itself works (with StopWhenUnneeded=true removed and upon manual start/stop and verification). It was installed by running `systemctl enable /path/to/file.service` As another variation, I tried to hook against sleep.target and hibernate.service with no luck. Any help very much appreciated (this of course includes completely different approaches). Best, Lukas ___ systemd-devel mailing list systemd-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/systemd-devel
