86 The directory is opaque when viewed through a union stack.
88 The file may not be renamed or deleted.

116 flags may be set or unset by either the owner of a file or the super-user.
121 flags may only be set or unset by the super-user.
122 Attempts by the non-super-user to set the super-user only flags
123 are silently ignored.
124 These flags may be set at any time, but normally may only be unset when
