53 An overlay filesystem combines two filesystems - an 'upper' filesystem
55 object in the 'upper' filesystem is visible while the object in the
57 merged with the 'upper' object.
59 It would be more correct to refer to an upper and lower 'directory
62 requirement that the root of a filesystem be given for either upper or
67 overlayfs. The upper filesystem will normally be writable and if it
78 upper and lower filesystems and refers to a non-directory in either,
