I've changed nothing since upgrading to F40 a week ago, yet I now find these errors in the journal:

/dev/zram0 exists and is configured:
Yes, and you can see it being disabled in the logs because you can't hibernate to RAM.
# swapon NAME TYPE SIZE USED PRIO /SWAP/swapfile file 48G 0B -2 /dev/zram0 partition 8G 512K 100
Do you have secure boot enabled?

No, however today's log is different:

Yes: simply replace ExecStart by ExecStartPre. This will make systemd-hibernate surely start after this script.
Thus:
$ cat /etc/systemd/system/hibernate-preparation.service [Unit] Description=Enable swap file and disable zram before hibernate Before=systemd-hibernate.service
[Service] SyslogIdentifier=%N User=root Type=oneshot
ExecStartPre=/bin/bash -c ' \ swapon -a; \ swapoff /dev/zram0; \ exit 0; \ '
[Install] WantedBy=systemd-hibernate.service
You don't need to specify an ExecStart.

I want to disable swap on zram0 and make sure it's enabled on secondary storage. Do you mean that will happen automatically?

I got that.

No: your hibernate-preparation script is needed.
systemd do not wait for an ExecStart command to finish before starting the next job (here systemd-hibernate.service).
On the opposite, it waits for an ExecStartPre to finish before executing the ExecStart.
I was wrong saying that an ExecStart was not needed.
Try thus that:
[Unit] Description=Enable swap file and disable zram before hibernate Before=systemd-hibernate.service
[Service] SyslogIdentifier=%N User=root Type=oneshot
ExecStartPre=/bin/bash -c ' \ swapon -a; \ swapoff /dev/zram0; \ exit 0; \ '
ExecStart=/bin/true

I'll try that, thanks.
