# E.g. on a Mac:
|
|
# ./setup-piForHeadlessConfig.sh /Volumes/boot

# or on Ubuntu:
|
|
# ./setup-piForHeadlessConfig.sh /media/$USER/boot

# chmod +x setup-piForHeadlessConfig.sh

# Put the card in your Pi, and reboot!

# Creates the ssh file if needed, since Raspbian now disables
|

# ssh by default if the file isn't present
