Offer Debian for smaller base image?

[benmccann]

I'm wondering if it would be helpful to use a smaller base image. Which OS you choose as a base to your Dockerfile can affect how long it takes to pull an image on a fresh machine. Using Debian instead of Ubuntu would save over 100MB. When I use dockerfile/java or any of the other images, there's really no benefit to having the larger Ubuntu instead of Debian even though I use Ubuntu for most of my day-to-day work.
