Whiteboard

[dzin Sept 26] moved to milestone 11.10
[asac, Sep 28, 2011] blueprints with high and essential not done don't get moved to next milestone without getting reviewed in company wide post-mortem.
[asac, Sep 28, 2011]: this is not going to happen it seems; needs to go through post mortem and a summary of packages that build and that do not build as well as instructions how to reproduce those builds/build-failures is due.
[rsalveti, Sep 29, 2011]: Instructions at https://wiki.linaro.org/Platform/DevPlatform/CrossCompile/CrossBuildNano, and quite easy to reproduce the builds. Not all the packages were ported, but most are working already, and the xbuilder-simple + the wiki makes it quite easy for people to try.
[dzin, Oct 3, 2011]: Bug #865547 has been logged against this blueprint to track unfinished items.

Headline: Linaro Ubuntu Natty Nano images are now cross buildable, making anyone able to cross build and customize it as needed.
Acceptance: Nano package list published at the wiki, fixes at the tools available at a PPA, cross enabled packages available at a PPA with proper instructions on how to cross build them, enough to generate the Nano image.
