Comment 9 for bug 1016776

I believe that Adam's proposed solution for buildds (bug #888665, which really ought to get fixed soon) is for them to ignore NotAutomatic, which will have the outcome that you desire.

It would be tricky to handle disabling proposed on upgrade to devel release and then re-enabling it for users when the release goes stable, which is what we would want to do since they have opted into testing proposed updates. And not possible for those who upgrade by editing their sources.list.

Having the NotAutomatic flag means that people can choose to take the hit for some particular update if they want to, but then they will be on their own.

Finally, this will be per-series, so you can always choose not to enable it for the devel series and implement whatever other mechanism for disabling proposed for these users. I still would like to see this enabled for those series too though, for the reasons I outlined above.

I plan to stop slacking on implementing this today. :-)
