How to install on an existing Debian system
Although the image builder supports a variety of architectures there may still be some which aren't supported. These especially include systems which have a proprietary boot blob, such as the Raspberry Pi boards.
It's still possible to install the system onto these unsupported devices if you need to. First you'll need to ensure that you have Debian Jessie installed and can get ssh access to the system. Once you have that then the installation of Freedombone is straightforward:
su
apt-get update
apt-get -qy install build-essential git dialog
git clone https://github.com/bashrc/freedombone
cd freedombone
make install
freedombone makeconfig
The installation process will then begin. Depending upon the hardware you're installing onto and your internet connection speed it may take quite a while to install.
