Maybe https://github.com/sbabic/swupdate is what you are looking for.
It has full OE support and is not tied to any architecture. You can extend
swupdate by scripting which will provide you with a lot of flexibility.

Correct. However, it currently assumes the specific BeagleB* partition layout 
for the SSD card. But that I would think could be adjusted for other other 
devices. They apparently also made some modifications to u-boot itself. I don't 
know what exactly those are though.

  hmm ... the client requirements are only that it use u-boot,
with the mender software integrated into u-boot. so if one can
configure and build that for powerpc, then install and boot u-boot on
the target board, why should it then be restricted to ARM?

  sure, their reference board is a BBB, but a quick glance at the docs
doesn't seem to say that it works *only* on ARM. must look closer ...

I am not entirely sure if I understand your requirements correctly but this 
https://github.com/mendersoftware/mender[1] could eventually be a starting 
point. The good news is that it already comes with YP/OE recipes and 
integration. However, it's currently only for ARM-based systems with u-boot.

Another approach, though still in its infancy and a simple PoC, is the GENIVI 
Software Management (SWM). At the core, there are SqashFS images that may 
contain partition images, software packages, configuration files, etc. together 
with a manifest (JSON) that instructs the SWM what to do.

  oh, darn ... i haz a sad. so it looks like i'm pretty well starting
from scratch, unless someone has pointers to anything i can use or
cannibalize to use as a starting point.

  basically, i'm after something that:

  * runs on powerpc
  * has the ability to scan the hard drive and decide what to do
about existing partitions, possibly preserving them
  * runs entirely standalone as it must be run on remote systems

the plan right now is to create a live linux image, and having to
pretty much manually do the above, so if you have any shortcuts, i'm
all ears.

  just to be clear, we're using WRL 8, and i found the docs related to
WRL's "Installer Image" a while back, but it's based on kickstart so
it seems pretty well exclusive to x86.

  if there's something equivalent that works for powerpc, i would be a
thoroughly happy camper.

In this case no. It is something simpler for a container OS, but it
does run from a bootable USB and has a simple backend that you can
customize for a given platform. The only trick is getting the right
bootable USB for non-x86.

  if any of that "installer tech" is relevant for powerpc, that would

This sounds like an installer MV has and that I have been given approval

It boots up from an iso image and runs a ncurses based interface that

install what ever image you built. It creates grub conf and installs it.
The installer bit is written in python.


If you do end up releasing it, I have some "installer tech" that runs
on non-x86 that I can see how it fits together.

  i realize that's a spectacularly imprecise request -- in a general
sense, it involves just starting with a regular image, then adding
utilities that run around doing all of the above, but if there's
anything that already takes one most of the way there, that'd be
great.



Does this sound like something you are thing about?

  given that it's based on grub, how compatible would it be with a
powerpc target? what i need is *specifically* for powerpc. and what
i'm after can't require a graphical interface, it needs to be
script-based as it will have to run on remote systems.

[yocto] any pointers to a yocto-based image to use as a live install utility?

[Robert P. J. Day]

  specifically in the context of powerpc systems, are there any
suggestions for an image that could be used to boot an older powerpc
system, running completely out of ram, and using that as an install
utility which would then be responsible for detecting/formatting a
hard drive, creating/formatting filesystems, downloading/installing
the OS, post-install configuration and so on?
