CMS is designed to have a static nucleus. Current version of MVS build
the nucleus from multiple sources, and two MVS systems IPL'd from the
same volumes need not have identical nucleuses. It would probably take
significant restructuring to allow MVS to IPL from a DCSS without
losing the flexibility it currently has.

Yes. Is there a business case for doing it?
>Is it actively being done?
Submit a requirement and IBM will probably tell you in the response,
or at least hint at the answer.

I vaguely recall hearing about a Linux DCSS.
