-.Fn
+The

 is implemented by inspecting the VFS name cache, and attempting to
 reconstruct a path from the process root to the object.
 .Pp
 This process is necessarily unreliable for several reasons: intermediate
 entries in the path may not be found in the cache; files may have more
 than one name (hard links), not all file systems use the name cache
-(specifically, most synthetic file systems don't); a single name may

 be used for more than one file (in the context of file systems covering
 other file systems); a file may have no name (if deleted but still
 open or referenced).
