initfs: packaging: Create a package to tell init to run from RAM Adding the obmc-phosphor-initfs-ram package will add the text overlay-filesystem-in-ram to /init-options-base which will cause init to not mount the rwfs. This allows building an image for booting over the network that will completely run from RAM, while allowing copy-files-to-ram to the kernel command line via bootargs will allow whitelisted files read from the rwfs before startup and allows them to be saved back to the rwfs via update.

OpenBMC uses Yocto/Open-Embedded for a build system, which supports an out-of-tree build. It is recommended that you create an empty directory somewhere to hold the build. This directory will get big.
On Ubuntu 14.04 the following packages are required to build the default target
sudo apt-get install -y git build-essential libsdl1.2-dev texinfo gawk chrpath diffstat
On Fedora 23 the following packages are required to build the default target:
sudo dnf install -y git patch diffstat texinfo chrpath SDL-devel bitbake sudo dnf groupinstall "C Development Tools and Libraries"
To start a build:
cd <builddir> . <repodir>/openbmc-env bitbake obmc-phosphor-image
