Hi, I see you have erlang-p1-pam installed, but if I understand you correctly, at the time when your ejabberd fails to start you still have the default config (ejabberd.yml) in place?
Please see README.Debian from the installed ejabberd package or here: http://git.deb.at/w/pkg/ejabberd.git/blob/refs/heads/stretch:/debian/README.Debian#l140 It tells you how to modify the systemd unit file to disable the NoNewPrivileges directive.
