Section Number and Name: 
Choosing a Graph Driver

Describe the issue: 
We would like to request documentation improvements regarding:

according to the docs[1], the recommendation is to use device-mapper thin pool?

"Red Hat strongly recommends using the DeviceMapper storage driver in thin-pool mode for production workloads."

Should the docs be upgraded/reworded, so the recommendation is overlayFS2 (since it has better design and performance)?
