I think there are a lot of related questions that could be turned in to umbrella questions.
How do I set environment variables for cron/upstart?
It could cover ruby, python, and bash for cron and upstart.
That way we could have one question/answer/set-of-answers to handle all upstart/cron environment variable questions.
This would enable something like redirecting this, that, and one of mine. I just think it would be cleaner.
