| An overlay filesystem combines two filesystems - an 'upper' filesystem | |
| and a 'lower' filesystem. When a name exists in both filesystems, the | |
| object in the 'upper' filesystem is visible while the object in the | |
| 'lower' filesystem is either hidden or, in the case of directories, | |
| merged with the 'upper' object. | |
