initfs: update: add option to perform checks but skip actual update

Provide a way to check if update is likely to succeed without
attempting actual updates.

This will check the image names correspond to mtd partition names,
and will be enhanced with additional checking for file size and
individual partition mounts.

This is not called --dry-run because it will still do file save
and restore if those are enabled.

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
