+A new array will normally get a randomly assigned 128bit UUID which is
+very likely to be unique.  If you have a specific need, you can choose
+a UUID for the array by giving the
+.B --uuid=
+option.  Be warned that creating two arrays with the same UUID is a
+recipe for disaster.  Also, using
+.B --uuid=
