This is a metabug for all the improvements we'd like to make to various pieces that help maintainer upgrade recipes. The task comes from this thread on oe-core list: http://lists.openembedded.org/pipermail/openembedded-core/2017-November/143983.html Paul, Ross, please add any dependent bugs I missed.
Let's reduce the scope of this a little bit. I've removed the bugs that are about improving the RRS web frontend; this metabug is now strictly about AUH and the underlying infrastructure (devtool, distrodata).
All the dependent bugs have been resolved; the code has been published here: http://git.yoctoproject.org/cgit/cgit.cgi/auto-upgrade-helper/ What remains is to take the new AUH into (unattended) use on the auh.yoctoproject.org machine; I have the necessary access rights, but haven't set it up yet.
So this is now all up and running, and produced it's first batch of results, which took about 30 hours or so to crunch: http://lists.openembedded.org/pipermail/openembedded-core/2018-January/146462.html The re-runs will happen every two months via cron.
