Just do:
apt dist-upgrade systemd-

That will let apt find the solution where it install systemd-tmpfiles but no
systemd itself.

The _correct_ way would be to write that dependency as
'systemd-tmpfiles | systemd' which is no-op on systemd installs but
avoids init switch elsewhere.

Don't.  My primary desktop is in the same situation, and it appears I risk
physical damage(!) whenever I attempt to boot systemd.
