 Les balises :
 - <FDTDIR> est automatiquement généré par le script ./mageia4arm/create_arm_img_urpmi.sh
- <UUID> est récupéré par le script ./mageia4arm/create_arm_img_urpmi.sh
+- <UUID> est récupéré par le script ./mageia4arm/create_arm_img_urpmi.sh , il peut être nécessaire d'ajouter une initrd pour utiliser l'UUID, autrement il faut spécifier /dev/mmcblkXpY .
 - <BOOT_ARGS> est défini dans le fichier ./mageia4arm/platforms/<LaPlateforme>/mageia4arm.cfg

+
+Il est possible d'ajouter la ligne `initrd /boot/initrd.img` si un fichier initrd a été généré par dracut.

 #### Autres
 Bien sûr, d'autres fichiers sont nécessaires. Il faut avoir l'arborescence du matériel (soit DTB/DTS, soit script.bin), le chargeur de démarrage spécifique à la plateforme ainsi qu'un noyau compatible avec l'architecture de la plateforme.

+- <UUID> is automatically reused bu the script ./mageia4arm/create_arm_img_urpmi.sh , it might be necessary to add an initrd in order to user the UUID, otherwise it should be specify /dev/mmcblkXpY .

+It is also possible to add the line `initrd /boot/initrd.img` if a initrd file has been generated by dracut.

 #### others
 Of course, other files are necessary. The device tree (DTB/DTS or script.bin) is necessary, a specific bootloader for the platform and a compatible kernel with that architecture.
