Contains files and tools to build the Sticky Pi OS. Briefly, we make a local image from the stock Archlinux operating system, then we transfer custom files on it before we use QEMU to spawn a virtual machine on this image. Once in the virtual machine, we install dependencies and continue the configuration of the virtual image. In the end. We compress the resulting image (YYYY-MM-dd_sticky_pi_rpi.img.gz) -- which can be burnt and used directly. The whole process is orchestrated by a Makefile

• src -- a small python package, sticky_pi_device, that will be installed on the Raspberry Pi
• .env -- definition of environment variables used at build and runtime (e.g. directory location, camera setting, ...)
• Makefile -- A tool to build the full image of a Sticky Pi. Needs to be run as super user under a linux system at your own risks.
• os_stub/ -- a directory mapping files to be copied to the root of the pi OS
• utils -- a set of scripts used during the image building process

To build the image:

sudo make all
