Important Notes
1. These instructions have been documented using Ubuntu 12.04 LTS as the reference operating system. It is advised that you also have the same setup.

2. Please make sure that you have at least 18GB of free space available as the source code can take up a lot of space.

3. It took 2 hours to build a systemd-image on a dual core I7 machine with 8GB RAM and only two(out of the possible 4) threads used.

1. Install the pre-requisites by typing the command below in the terminal:

sudo apt-get install gawk wget git-core diffstat unzip build-essential chrpath libsdl1.2-dev xterm unzip texinfo \ git texi2html subversion ncurses-dev sed cvs git-core coreutils docbook-utils python-pysqlite2 help2man make \ gcc g++ desktop-file-utils chrpath dosfstools kpartx bitbake

 * 1) Add this to the bottom:

4. Setup the necessary environment for MinnowBoard by typing the command below in the terminal:

MACHINE=minnow ./oebb.sh config minnow 5. Build the image by typing the following command in the terminal:

MACHINE=minnow ./oebb.sh bitbake systemd-image

6. The resulting image will be located in /setup-scripts/build/tmp-angstrom_v2012_12-eglibc/deploy/images/minnow/
