Failed ejabberd Installation?

NethServer Version: 7.8.x
Module: web server, mail server, nextcloud, webtop, firewall, deep thread, ips, fail2ban

Hi, after installation, I checked the installation and recognized…

 [root@ns-srv01]# rpm -Va | grep missing
    missing     /opt/ejabberd-20.03/conf
    missing     /opt/ejabberd-20.03/conf/cacert.pem
    missing     /opt/ejabberd-20.03/conf/dhparams.pem
    missing     /opt/ejabberd-20.03/conf/ejabberd.yml
    missing     /opt/ejabberd-20.03/conf/ejabberdctl.cfg
    missing     /opt/ejabberd-20.03/conf/inetrc
    missing     /opt/ejabberd-20.03/conf/server.pem
    missing     /opt/ejabberd-20.03/database

Is this common?

Sincerely, Marko
