After further investigation, I found the source of my issue. Basically the / directory had the wrong ownership. Not sure how I did that but it seemed to have the side-effect of making systemd-tmpfiles not create directories as it should.
I saw messages like this in the log that clued me in. May 09 21:11:49 x1 systemd-tmpfiles[1665]: Detected unsafe path transition / (owned by charles) → /tmp (owned by root) during canonicalization of /tmp. After a chown, ls -ld / now shows ownership by root:root correctly and I no longer get errors in the log.
