Comment 2 for bug 1316796

I merged Didier's patches into our package now, as they won't make it into 219 any more (bug fixes only), and the 219 release itself is still some weeks out, so that won't make it into our feature freeze either.

Great work, thanks Didier! I noticed that Control-C doesn't work to interrupt the check, but the aggregation and plymouth feedback works very nice now.
