Build system and repos for F11/XO-1.5?

I am starting to work with deployments on how to respin our F11/XO-1.5
OS. What is the current build system for the F11/XO-1.5? Are we still
using livecd-creator? Or dsd's new toy (for which I haven't found the
code or the doco yet)?

BTW, if instead of re-spinning an image (like image-creator does) we
tel them to use our same build infra, we *must* keep the repos for
each release published and stable for a long time. IOWs our builds
need to be reproduceable for years to come.

cheers,

m

We're using dsd's new tool, which is:

http://dev.laptop.org/git/projects/olpc-os-builder
http://dev.laptop.org/git/projects/olpc-os-builder/tree/doc/README
http://dev.laptop.org/git/projects/olpc-os-builder/tree/doc/README.devel

To reproduce the latest 10.1.1 build:

# python osbuilder.py examples/olpc-os-10.1.1-xo1.5.ini

Excellent, thanks for the confirmation.

Right. I will have to work on it to...

 - provide an example kickstart / ini that sets all the config values
needed for a deployment; see
http://wiki.laptop.org/go/User:Martinlanghoff/Key_Autonomy:_Preparations_for_local_OS_image

 - provide an easy way to sign all the components for deployments that
use key autonomy

cheers,

It's already got one of those -- see modules/signing/README.

gawjus! Thanks Daniel and Chris for the responses.

I'll happily do maintenance and further documentation, as it's right
up my alley.

WRT to Fedora RPM upkeep, I might look for a co-packager that is part
of Fedora proper. Keeping track of current packaging practices,
deadlines and other distro-centric minutiae is a job onto itself.

cheers,

To Daniel,

couple questions about it...

 - Can it build F11/XO-1 images, with jffs2?

 - Can it build "partitioned" images?

 - I see the stern warning about running the compose on the same OS as
OLPC does. Are there specific things that blow up? Should we generally
recommend that the compose is run on the same OS that is being
composed? (F11 for F11-based OSs?)

To Chris,

If I look at examples/olpc-os-10.1.0-xo1.5.ini, there are 3 yum repos,
are the 3 of them frozen? In other words -- can anyone match our build
now and in 2 years' time?

cheers,

m

Yes, it is used for Steven's recent F11-XO1 releases

Yes, it has been used for all recent XO-1.5 OS builds which are partitioned.

I don't know what the effects (if any) would be if you tried to build
10.1 from non-F11, I have not tried but I don't think its a good idea,
hence the warning. Investigation welcome.

You also need to match the olpc-os-builder version to the build that
you are making, since some of the sauce that makes the build is
specific to the build scripts at a certain point of time. This
specific point might have been overlooked for 10.1.1 - is it
officially released? If so the olpc-os-builder tree should be bumped
and tagged as v1.1.0 at that specific point, and suggested_oob_version
in the 10.1.1 build config should be set appropriately.

Yes, see modules/jffs2_image/README.

   >  - Can it build "partitioned" images?

I think 1.5 images are always partitioned, 1.0 images are always not,
looking at the code (modules/sd_card_image/ for 1.5).

That's what I've been doing.

Yes, frozen.
