d'ailleurs il me semble que c'est sur une idée de qqun d'ici
gizmo ? le preseed.cfg est sur un serveur http chez moi (comme le paquet vmware tools renommé hors version VMwareTools.tar.gz)
et j'ai modifié juste le démarrage d'un iso pour le prendre en compte
+ miroir debian local
compte root/pass et user/pass
a adapter pour vous
rien de révolutionnaire vite fait mais j'en avais marre de faire l'install à la main
