I need this for porting comm-central to taskcluster, so the image referenced by gecko's .taskcluster.yml doesn't need to be updated. It may make sense to update it anyway to avoid later confusion; in which case the additional changes done in bug 1350045 also need to be done to avoid breaking chain-of-trust.

Actually, the changes from bug 1389715 are probably important to pick up too.

I'm running quite behind on getting stuff done but I'll put this on my queue. If someone steals it before I get to it, that's great :)

going to take a stab at this one and see if I remember how to do this :)

I have permissions to push the Docker image for the decision image if you need my help.

try push using new decision task: https://treeherder.mozilla.org/#/jobs?repo=try&revision=699593f7c6c38c4d71f07b08b5ba2969561b4f35&selectedJob=123941666

Comment on attachment 8898439 [details] Bug 1391288 - Rebuild decision task image with new robustcheckout https://reviewboard.mozilla.org/r/169820/#review175040 Don't forget to coordinate with aki to get the new image hooked up to chain of trust. This can't land until that's done.

Published "taskcluster/decision:0.1.9@sha256:9d6a38ff675ba2f2f132bc1461e3a48b0ce56c90617a8a5c5f8c48c6eb8d06e0" and submitted patch for review containing this new image. Image was built off of the most recent mozilla-central. This cannot be merged until puppet and scriptworker are updated.

This same hash needs to be added as a puppet patch too, which I have never done.

Comment on attachment 8898439 [details] Bug 1391288 - Rebuild decision task image with new robustcheckout https://reviewboard.mozilla.org/r/169820/#review175044 I believe you! :)

Landed on https://hg.mozilla.org/build/puppet/rev/1b02d9e56bed ; merged to production. Once that rolls out we should be good to land in-tree... within the hour I believe.

Circling back on this, did all the prerequisites of the in-tree changes land now? If so, we should be able to land this.

gps, thank you for landing this.
