The flag was gated on the admin database not existing yet, treating the file's presence as proof the admin user had been created. It is not: PZ creates the DB file in ServerWorldDatabase.create() before it creates the admin user, so a boot interrupted between the two leaves a database with no admin in it. After that the guard withheld -adminpassword on every subsequent start, the server fell back to an interactive "Enter new administrator password:" prompt, read EOF because a detached container has no stdin, and died with NoSuchElementException. systemd restarted it into exactly the same state, 50 times, which is how this was found. Passing it unconditionally costs nothing when the admin already exists and removes the deadlock entirely. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
