> Conference Day 2 ---------------- Day two continued with user

> of a Ganeti web manager, the "~okeanos Public Cloud Service" and

> upstream. It has been scheduled to be fixed in the next version.

> Conference Day 3 ---------------- Day three started with a
> discussion about reducing the need of the "root" user within
> Ganeti. Several suggestions have been made, from using sudo for all
> the calls that need root to chroot'ing the daemons. Also discussed
> was the need to address the need to monitor ganeti nodes but to
> avoid spawning the monitoring processes frequently.
> The second discussion was about Deploying & Managing Instance
> Images and how to improve the status quo. This discussion was quite
> heated and no real solution that suits all needs had been found
> until the lunch break.
> I needed to leave the conference at that point, as I needed to
> catch my flight back to Germany. Skroutz and Google talked about
> "Build System Overhaul and Upgrades" and GRNET about "Disks as

> Conclusion ---------- All in all it was a very successful
