Thanks, Michael. I tried your test packages, and the first thing I
noticed is that the shutdown messages are no longer visible; instead,
I see some corrupted fragments of the startup messages (screenshot
attached). The system still rebooted after a couple of seconds as
expected, though.

Anyway, I'm running with the persistent journal enabled, so I was able
to look at journalctl -ab-1. Most of the errors are gone, but the
final error, about systemd-cryptsetup at vda5_crypt.service, remains.

Strangely, I see no mention of any kind of fsck of / in any of the
journals -- might you happen to know why that would be, or how I can
verify whether or not it was found to be clean? (I see the fscheck for
/boot, on /dev/vda1, but not / on /dev/mapper/stretch--vg-root.)

I've attached the full output of journalctl -ab-1, which is with your
test packages, as well as the same from the last boot without them. To
summarize, these are the errors that are no longer present with your
changes:

And these are the ones that still are:
