Building

To generate an image, run the build.sh script as root:

::

$ sudo ./build.sh

There are some environment variables that you can set to customize the build:

IMAGESIZE Target size for the image in MB (default: 2000) BOOTSIZE Size of the /boot partition in MB (default: 64) DEB_RELEASE Target Raspbian release, can be stable, testing or unstable (default: stable) DEFAULT_DEB_MIRROR Repository URL to grab packages from (default: http://mirrordirector.raspbian.org/raspbian) USE_LOCAL_MIRROR For use with apt-cacher-ng, can be true or false (default: false) SSH_KEY Public key to enable SSH Login for (default: ~/.ssh/id_rsa.pub) DEBUG Drop into a chroot shell after the image has finished building (default: false) FROM_TARBALL Path to a spreads tarball created by python setup.py sdist. If unset, install from Raspbian packages.

The image will generate a rasbpian image with up-to-date packages and spreads pre-installed and pre-configured (for use with Canon A2200 cameras running CHDK). On the first boot, the image will resize itself to fill all of the remaining space on the SD-Card and reboot shortly thereafter. Spreads will be automatically launched on startup. Make sure that your devices are turned on before the boot has finished.

Login accounts:

• root:raspberry
• spreads:spreads

The spreads user is allowed to run all commands with superuser privileges through sudo.
