| 4 | An overlay filesystem combines two filesystems - an 'upper' filesystem |
| 5 | and a 'lower' filesystem. When a name exists in both filesystems, the |
| 6 | object in the 'upper' filesystem is visible while the object in the |
| 7 | 'lower' filesystem is either hidden or, in the case of directories, |
| 8 | merged with the 'upper' object. |
