I think there are a lot of related questions that could be turned in to umbrella questions.  
  
One example:  
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][1], [that][2], and [one of mine][3].  I just think it would be cleaner.
