This script will make some small but necessary changes to a default Raspberry Pi OS (previously called Raspbian) image.

In episode hpr2356 :: Safely enabling ssh in the default Raspbian Image I walked through the first steps of automating the update of this base image. It will:

• Download the latest image zip file
• Verify it is valid
• Extract the image itself
• Enable ssh for secure remote management
• Change the default passwords for the root and pi user
• Secure the ssh server on the Pi

Since then I improved the script to:

• Enable connections to your WiFi network (wpa_supplicant.conf)
• Load it's configuration from a ini file keeping sensitive information separate from the main script.
• Using losetup to greatly simplify the mounting of the image.
• Creation of a First Boot script.
