Créer un point de montage qui ne pourra être utilisé que s'il est mounté:

# mkdir -m 000 /mnt/mountage

“… create mount points with permissions 000 to prevent data from accidentally being written to the directories when the partition is not mounted; any files living in the mount point will be hidden when the partition gets mounted, and making it non-writable, is a good way to help prevent that. ”
