init: Run from RAM if file system type is specified as none

Allow file system type none for rwfst, which means do not mount a
separate file system but just use the directory in the tmpfs /run.

This will be used to allow the flash controller to not be used by
the running image, allowing flash updates while the BMC is running
the main application.

It could also be used for a file system less prone to corruption
where the read-write overlay is only updated with whitelisted files
at specific points in time with updates to the update script.

Build Status

Building

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
