Build FOG file system with BuildRoot

In order for the FOG Client to boot on the hosts, it requires a kernel and a filesystem image containing its filesystem. Buildroot helps building the toolchain (uclibc) and generate that image with busybox and all the packages we need. This page will tell you how to build the filesystem on your own from SVN.

Debian 7

Debian update

sudo apt-get update
sudo apt-get upgrade

Download Buildroot

wget http://buildroot.uclibc.org/downloads/buildroot-2014.08.tar.bz2
tar xjf buildroot-2014.08.tar.bz2

Copy source to Buildroot

cp -r fogsvn/buildroot/* buildroot-2014.08/
cd buildroot-2014.08
mv fog.buildroot.config.32 .config # or config.64 for 64 bits

build FOG file system

make menuconfig
# This will download all the required packages from their sources, it's around 300 MB
make source
# All packages are now in buildroot-2014.08/dl/ So we compile:
make
# Here is our init.xz
cp output/images/rootfs.ext2.xz init.xz

copy init.xz to your FOG server /tftpboot/fog/images/init_32.xz (or init.xz for 64 bits)
