Hehe, indeed I did cherry-pick huge parts of your PR :)
@NicolasRitouet could you say a word or two about the why of your request? I can certainly port it over, but then again this would just add a totally new dependency to deployd for sth. that's already working fine without a dep. As I said, I'm fully open to it, just thought maybe you could shed a light on your reasoning. Are there any plans to use more of bluebird anywhere in deployd as of this moment?
