initfs: shutdown: comment on update success

Print an error from the shutdown script when the update fails.

Update is changing to return codes when its preconditions are not
met, so be more verbose about its success to provide a means to
debug flash updates not occurring.

We could add a sulogin or sushell but its not clear what would be
desired here.  If so the message should include "rmdir /oldroot
to get a PID 1 shell" like /takever works in init.

Build Status


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
