+Description:
+               It shows the abolute path of XINO (External Inode Number
+               Bitmap, Translation Table and Generation Table) file
+               even if it is the default path.
+               When the aufs mount option 'noxino' is specified, it
+               will be empty. About XINO files, see the aufs manual.
