[rsalveti, Jun 26, 2012] Riku sent his current status over email, but didn't get implemented in time as he left for a long vac. Should be moved back to backlog.
[dzin, jun 29, 2012] Moved to backlog
[dzin, July 17, 2012] Move to 12.08
[dzin, Aug 16, 2012] This is at risk for 12.08 delivery because of resourcing.
[rsalveti, Sep 4, 2012] This is linked with, so it might be good to put some to focus on it asap.
[rsalveti, Sep 9, 2012] Also, let's not be blocked in case it's too hard to get this fixed properly at Debian/Ubuntu at this point, as at this moment we just need a working solution so we can properly bootstrap the rootfs. Once we get a working rootfs, moving to a native environment with a fastmodel would be the best working option.
[rsalveti, Sep 26, 2012] Riku, please update your status on this blueprint, explaining what was and what wasn't done, and how we should continue the remaining work.
[dzin, Sep 28, 2012] Need confirmation on status. Moving to 12.10.
[rsalveti, Oct 24, 2012] dzin, mind checking with riku and wookey about the status of this blueprint? Thanks.
