title: Modify Debian image for raspberry pi
body: <p>I need to modify a Raspbian image for use with Raspberry Pi's in a commercial setting. This way I won't have to modify the defaults of every single pi afterwards. I want to set the default keyboard to U.S., disable auto-login and boot to command line rather than GUI. Is it possible to modify an image with these settings before flashing each card? If so, how?</p>
