> In the 0.30.0 release, the Mesos Agent will no longer implicitly pass along its environment variables (see: http://mail-archives.apache.org/mod_mbox/mesos-dev/201603.mbox/%3CCAK7AWaGB24ALh8eb%2BvKMFgc4%2BjmhxZ6ry79HBcKN%2BBt04Sx43A%40mail.gmail.com%3E).
> I tested in vagrant by explicitly setting the {{--executor_environment_variables}} flag on the agent to {{'{}'}} and verified that this does impact us. Initially we get a permission denied error when trying to fork the runner:
