Nous sommes dès à présent en possession d'un véritable LINUX FROM SCRATCH. Nul besoin à priori de lui changer quoi que ce soit. Si néanmoins c'était le cas, nous verrons comment réinstaller net OS dans la partie suivante.
Remarque: le système de fichier est monté en lecture/écriture sauf pour les répertoires au contenus volatiles comme /var/ afin de ne pas 'user' la mémoire FLASH.
