Why bother with a copy.  Just leave it in zFS and adjust DD statements
in subsequent jobs as needed.

With regard to John M.'s concern of "untold damage", the perpetrator
can do nothing that couldn't be done by logging on to the z/OS account
and executing the command there.

If a security administrator has disabled shell on that z/OS account,
there remains the need to similarly disable BPXWUNIX.  Best just to
limit the capabilities of that z/OS account:  Protect the resources;
don't rely on locking tools.  That's how RACF works best.
