DESCRIPTION="Automount USB drives by plugging them in"
INFOTITLE="Automount notes"
INFO="Plugged in USB drives will be automounted under /media
on boot or at the moment of insertion.
Format your drive as ext4 in order to move NC datafolder or database
VFAT or NTFS is not recommended for this task, as it does not suport permissions
IMPORTANT: halt or umount the drive before extracting"
