I vaguely recall that Docker checks the success of commands, but I'm not completely certain if that's why we combine them.

I feel like the order of execution is important, but I thought Docker always runs commands in the order they appear.

I remember something about Docker creating a new layer for each RUN statement, so maybe it's to avoid that?

Ah, I see now. Combining the commands in a single RUN statement is more efficient than using multiple RUN statements. That makes sense.

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!
