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.

No, however today's log is different:

Yes: simply replace ExecStart by ExecStartPre. This will make
systemd-hibernate surely start after this script.
Thus:

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

Yes,that makes sense.

I'll try that, thanks.
