CentOS Stream is built from the currently released RHEL Source Code + 0.1

So if RHEL 8.3 is released .. Stream is the Source Code (built) that
will become 8.4 in a few months.

If this statement is exactly correct, then I think a lot of the issues in this
thread may be easy to address.  However, the question is whether it is really
"That will become"
or actually
"That might become, if it turns out to be stable enough,"

I.e., to me the critical question is how often (in practice) will updates that
have problems, and will not actually make it into RHEL, end up in CentOS Stream.
Presumably all such updates will be superseded in Stream by corrected ones,
before they're in RHEL.

In fact, would it be possible, to list the final versions of each package's
update at the moment of the RHEL release, and only do the CentOS Stream update
based on that list?

Noam

There is one source for the source code that will be used.  While in
stream it will iterative (the push a bunch of changes today .. the build
those change today).  Those go through a CI process and get released
into stream.

When it comes time to build rhel 8.4 it will come from the same source code.

What should be also taking into account:
- There is no "CentOS" (Linux or Stream does not matter)
that have a life span of 10 years. Centos Stream 8 will
be retired and deleted from the mirrors end of May 2024 Q1!
