> Part of the image provisioning process is to call a backend to create a root filesystem based on the image on disk layout.
> The problem with the copy backend is that it's both waste of IO and space, and bind only can deal with one layer.
> Overlayfs backend allows us to utilize the filesystem to merge multiple filesystems into one efficiently.
