I was not referring to the Fedora mechanism.  Some licensed-for-fee 
commercial unix environments (not linux) used on primary servers allow 
for major release upgrade in place.
Does the Red Hat method that is mentioned by Red Hat allow for this, or 
is the Red Hat enterprise z-stream "insane" to use in a production 
situation?

If it is not insane but actually is effective, are there no Linux or GPL 
encumbrances on z-stream that "force" Red Hat to release the source?
