2GBSD card to install this image(Sorry to those who had 1GB it really didn't work well long term on such a small card and I ran out of time!) Also this does NOT work with an RPi3
Updated April 13th, 2015.
A bootstrap script is included that will install required users and software. It has been tested on several devices including RK3188 (ARM), BananaPI (ARM), Raspberry PI (RPI-GPU) and a basic Linux. To use install your Operating System of choice and then login and run the following commands. Requires your user to have sudo access or be root.
wget http://ognconfig.onglide.com/files/v2.0/bootstrap -O bootstrap
chmod +x bootstrap
This script installs the software using the instructions at http://wiki.glidernet.org/wiki:raspberry-pi-installation. The bootstrap will create a user called 'ogn' and will install the service to run from that user directory. It should not interfere with other software installed on the machine. It includes an auto-update script which is downloaded from the OGN Config server please see the note below for security details.
NOTE: The installation will also include the 'automatic update script'. This is a signed script downloaded from here that runs every night as root. The script is able to update any aspect of the device, though the purpose of it is to install the latest version of the OGN software. Updates to the script must be signed by a secret key that is not stored on my webserver without this signature any updates will be ignored. This protects against man-in-the-middle attacks, corrupted downloads and web server compromise.
If you would rather not use the auto-updater please run sudo crontab -e and remove the update line.
