The main mechanics of OverlayFS relate to the merging of directory access
when both filesystems present a directory for the same name. Otherwise,
OverlayFS presents the object, if any, yielded by one or the other, with
the "upper" filesystem taking precedence. Unlike some other overlay
filesystems, the directory subtrees being merged by OverlayFS do not
necessarily have to be from distinct filesystems.
