This try push didn't work: we need both the yaml changes and some code in signing.py to actually use it. https://treeherder.mozilla.org/#/jobs?repo=try&revision=bbd1c5e8aacb https://hg.mozilla.org/try/rev/bbd1c5e8aacb04b16c0bb998e2174d059fae0e8e

Also should fix the issue with the Linux opt builds on tc not appearing with the rest of the linux32 builds on tc. https://public-artifacts.taskcluster.net/Ms0oqNXaR4qZQTmc3ucuNA/0/public/full-task-graph.json https://treeherder.mozilla.org/#/jobs?repo=try&revision=d3dae48c69cd28f5a6850bf7921b983b481f7cc7

Linux32 jobs don't have aren't associated with the right platform so they aren't showing up on treeherder https://public-artifacts.taskcluster.net/RJEjm-AhThy9Pdl0ug-MKg/0/public/full-task-graph.json https://treeherder.mozilla.org/#/jobs?repo=try&revision=662b925f74ef668d2c527c07d21243a4ae3c856a&selectedJob=29283952

Comment on attachment 8801863 [details] [diff] [review] bug1306166th.patch Hm. This makes me wonder if we should rename all the 'linux' as 'linux32'. Not a blocker, though.

patch to so signing jobs have same th platform as build job and are co-located on the same line https://treeherder.mozilla.org/#/jobs?repo=try&revision=e20e7db92cf5cf2216ad4128d7b984b31d15bbc5 https://public-artifacts.taskcluster.net/GOncI6ZtTzmn-nPTZEmedg/0/public/full-task-graph.json I fixed the lint error since the try run

Comment on attachment 8801941 [details] [diff] [review] bug1306166th2.patch Thanks for working on this! For windows and osx I think it'll be important for signing to happen per CI build, which will allow us to catch signing errors early on instead of at nightly or release time. Having the jobs visible is an important piece to noticing if the jobs are running+succeeding.
