Utiliser le fichier /etc/rc.local pour ajouter des commandes.
Attention a rajouter un "&" a la fin pour les commandes longues.
Il est préférable d'utiliser un script Systemd.
Extrait de stackoverflow:
The script /etc/rc.local is for use by the system administrator. It is executed after all the normal system services
are started, at the end of the process of switching to a multiuser runlevel. You might use it to start a custom service,
for example a server that's installed in /usr/local. Most installations don't need /etc/rc.local, it's provided for the
minority of cases where it's needed.
