+Preserve inode numbers from the underlying filesystem.

+Without this option, FUSE makes up its own inode numbers.  The inode
+numbers you see in L<stat(2)>, C<ls -i> etc aren't the inode numbers
+of the underlying filesystem.

+inode numbers appearing through FUSE.  Use of this option can confuse
+some software.
