Istinctively, I don't like the idea of splitting up the hypervisor project in multiple projects. I am no voting expert, but maybe we could consider explicitly weighting each project differently. The advantage is that the mechanism would be obvious rather than implicit. For example "Project A = 10" and "Project B = 6". In the previous example: project A, weight 6, leadership team size 2, total positive votes 2, 100% project B, weight 10, leadership team size 12, negative votes 8, positive votes 4, 33% Total favor: (100*6 + 33*10) / (6+10) = 58.12 -> fail The problem is how to come up with the numbers in the first place and how to update them when necessary, to reflect changes in maturity, size and activity of a project. For the sake of updating the document and moving forward with the other, more important, changes, could we postpone modifications to project wide changes? Or just separate them out to a different patch so that most people can give their +1 to the other patches? _______________________________________________ Xen-devel mailing list Xenfirstname.lastname@example.org https://lists.xen.org/xen-devel
