drop_symlink unlinks as root (rm on the final component never follows the target and the customer cannot deny it) and refuses to start if the path is still a symlink. user_touch refuses unless it ends up a regular file. New require_safe_logs runs immediately before httpd / php-fpm start (they open files under /home/$user/logs as root): logs/, logs/apache, logs/php-fpm must be real directories and nothing under logs/ may be other than a regular file or directory, else the entrypoint exits 1 without starting any daemon.
