- tristate "Overlay filesystem support"
- help
- 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.
- For more information see Documentation/filesystems/overlayfs.txt
