Overlayfs is a relatively new filesystem which implements copy on write semantics at the file level. It is specially gaining popularity in the container world where container technologies like docker are using overlayfs for image and container storage.

This talk plans to give an overview of overlayfs design, what are some of the outstanding concerns and what is being done to address those upstream. It also provides some details of how docker makes use of overlayfs and how it provided some significant speed up w.r.t
