I bet the folks who wrote this question are just waiting for someone to say 'apt-get install fortune-cookies' as the answer. That would be a real knee-slapper!

Hmm, this is a good one. I wonder if the folks who wrote this question have a sense of humor. Maybe they'll throw in a joke about 'apt-get install fortune-cookies' or something.

But wouldn't combining the commands in one RUN statement reduce the number of images created?

Wow, this is a tricky one! I'm not sure if Docker executes all RUN statements in parallel or not. Let me think this through...
