Le code de retour est le suivant :
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>
# / was on /dev/sdb5 during installation
UUID=7905ed1d-c65b-42de-b581-5b04d73787b1 / ext4 errors=remount-ro 0 1
# /boot/efi was on /dev/sdb1 during installation
UUID=30B8-8812 /boot/efi vfat umask=0077 0 1
/swapfile none swap sw 0 0
/dev/disk/by-uuid/E424B7B324B786D8 /mnt/E424B7B324B786D8 auto nosuid,nodev,nofail,x-gvfs-show,rw,user,auto,exec,gid=1000,uid=1000,umask=002,utf8,codepage=850,shortname=mixed 0 0
C'est la dernière ligne qui a été ajoutée. J'ai rejouté plein d'options après car les options par défaut ne changeaient rien.
