# psx-pi-smbshare automout-usb script
#
# *What it does*
# This script configures raspbian to automount any usb storage to /media/sd<xy>
# This allows for use of USB & HDD in addition to Micro-SD
# It also creates a new Samba configuration which exposes the last attached USB drive @ //SMBSHARE/<PARTITION>

# Update packages
sudo apt-get update

# Install NTFS Read/Write Support
sudo apt-get install -y ntfs-3g

# Install pmount with ExFAT support
