Given the use of CentOS 8 stream, I am curious about support and 
"hardening".  Some of the Fermilab and CERN machines are connected to 
the outside Internet (WAN), including (as I recall) some of the 
connections between CERN and the various EU, USA, etc., HEP 
collaborators (although over VPNs within the collaborations if memory 
serves, pursuant to any restrictions from governments not being able to 
surveil all traffic within the jurisdiction of those governments that 
fully surveil everything).  Is Fermilab/CERN/other HEP collaborators 
providing the support needed to convert CentOS 8 stream into an 
"enterprise production" environment?  I assume that as new releases of 
stream (semi-beta) are released, there are test platforms identical to 
production machines at both CERN and Fermilab, and that the test 
platforms are *NOT* used for data collection, analysis, communications, 
etc., but upon which it can be determined if the latest release is 
sufficiently stable for vital production work.  Likewise for the various 
security updates as these are released.
