Just so that the SL list has a specific inclusion of this information 
(in the event the CentOS lists somehow become unavailable), below is the 
last item in the above set.

Hi Everyone,

We would like to welcome onboard the CERN Linux Distro team (
http://cern.ch/linux  ) to the CentOS Core SIG. Thomas Oulevey and
Jaroslaw 'Jarek' Polok are going to be bootstrapping the CentOS
Community Buildsystem around Koji and helping run it going forward. The
community buildsystem is going to be the central place for all source to
binary builds used by all efforts other than CentOS Core ( for now ).

The initial target is to get a test instance running in the coming
weeks, and then work on the git.centos.org integration, with the aim of
having the 'production' buildsys online soon. This is the build service
that all SIG's and Core SIG builds will consume going forward ( with the
exception of CentOS Linux, we have quite a bit of work to do before we
can migrate that ).

Communications on this effort will be on the centos-devel mailing list (
http://lists.centos.org/mailman/listinfo/centos-devel  ) and on the
#centos-devel irc channel on irc.freenode.net.  Hardware resources for
the effort have been identified, setup and access is being setup so
things can start rolling fairly quickly. Mike McLean and Fabian Arrotin
are going to be working with them.

You can keep up with Jarek on his google+ page at
https://plus.google.com/+JaroslawPolok/  and Thomas tweets at
https://twitter.com/thomasnomas  ; They both also contribute to the
http://linux.web.cern.ch/linux/  blog.

Please join me in welcoming Thomas and Jarek to the CentOS Project.

Several questions:

1.  Is CERN linux the same as SL?

1.1 Are any of the Fermilab team doing the same as in the posting from Singh?

2.  Evidently, Singh and other "core" CentOS team members actually are Red Hat employees,
just as the core SL team have been Fermilab or CERN employees (presumably in some cases
actually paid by the research collaborations funded by various government agencies through
various universities -- e.g., in the USA, NSF or DOE with each PI typically holding a
tenure-stream faculty position at a university).  Will the core SL team or the core CERN linux
team likewise become Red Hat employees?

2,1  As Red Hat employees, one assumes their primary loyalty are to and directions come from
their corporate employer.  Is this consistent with a SL-type distribution in which the user
community (such as the CERN LHC collaborations) have ultimate needs, not those of a for-profit
corporation?

3.  Will SL just be a SIG of CentOS?
