In Docker, migrate runs as root while data/ belongs to www-data, so a planted data/admin_password symlink would make root overwrite its target. Remove any existing path first and create the file with O_CREAT|O_EXCL|O_NOFOLLOW (mode set via fchmod). install.sh's /tmp fallback log is now created with mktemp instead of a fixed name.
