• what's the scopes problem with new tc-worker y-2012 (https://treeherder.mozilla.org/#/jobs?repo=try&revision=c2a12e796c42&selectedJob=16774445)

  solution: add scope (queue:create-task:aws-provisioner-v1/y-2012) to role (https://tools.taskcluster.net/auth/roles/#moz-tree:level:1)

• how do you differentitate worker types for try vs build (https://bugzilla.mozilla.org/attachment.cgi?id=8719743&action=diff#a/testing/taskcluster/tasks/windows_build.yml_sec1)

  solution: set the worker type somewhere under: https://hg.mozilla.org/try/file/c2a12e796c42/testing/taskcluster/tasks/branches/try

• how do we manage termination of idle instances?

solution: provisioner should handle this by only spinning up instances as required. Still need to understand why all y-2012 instances stay up always.
