/var should be unmounted later, after the final killing spree by systemd-shutdown (see man 8 systemd-shutdown). I don't suppose you actually had a dirty fs after shutdown? As for /var being unmounted earlier during shutdown, this is most likely happening because of var.mount conflicting with umount.target and systemd-journald.service not having an explicit ordering against var.mount I suppose you have persistent journal enabled, i.e. journald is writing to /var/log/journal? Fwiw, I think the warning is harmless (as said, systemd-shutdown will unmount /var). -- Why is it that all of the instruments seeking intelligent life in the universe are pointed away from Earth?
