Why would anyone want to use CMS formatted volumes? That suggests that
someone is going to have an mdisk that starts on real cyl 0 and allows the
owner of the mdisk (volume) to change the real vol serial. There is simply
no reason at all to allow that. Even if you say that real cyl 0 is going
to be an mdisk owned by a $ALLOC$ type of userid, why would you want to
format it using CMS. CP and MVS are real operating systems. Give them
real operating system labels and VTOCs.

Right. CP vols. But z/OS doesn't like CMS formatted volumes.
While CP is happy with full-volume CMS content, last I heard
z/OS still got heartburn over it. I would be glad to hear
a report that this is no longer true.
