Arg, unfortunately that wasn't the problem. I'm not sure now, why it
worked. The real issue is that systemd-tmpfiles-setup.service has:

ConditionPathExists=/etc/tmpfiles.d

I don't have /etc/tmpfiles.d, only /usr/lib/tmpfiles.d, so it's skipped.
I think this should be:

ConditionPathExists=|/etc/tmpfiles.d
ConditionPathExists=|/run/tmpfiles.d
ConditionPathExists=|/usr/lib/tmpfiles.d

or something like that.

Regards,
Michael
