To make to GPIO port available and run The Link Box at boot up...

Do "sudo nano /etc/rc.local" to edit that file. This is what mine looks like:

--- cut here --- cut here --- cut here --- cut here ---

$ cat /etc/rc.local 

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

# Print the IP address
_IP=$(hostname -I) || true
if [ "$_IP" ]; then
  printf "My IP address is %s\n" "$_IP"
fi

# start tlb
#echo "Starting GPIO"
echo "17" > /sys/class/gpio/export

echo "out" > /sys/class/gpio/gpio17/direction
chmod 666 /sys/class/gpio/gpio17/value
sleep 1
echo "Starting TLB"
sleep 1
/usr/local/libexec/tlb -f /home/tlb/tlb.conf

exit 0
