le fichier cmdline a bien été modifier automatiquement et le quiet splash(le carré welcome) est supprimé voici l’original
dwc_otg.lpm_enable=0 console=serial0,115200 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait quiet splash plymouth.ignore-serial-consoles
