The 800lbs gorilla in the room is CERN (and other large physics labs), who require a linux (some linux) to run the large compute farms for analysis of LHC data. For historical reasons, this linux has been Red Hat based (and we know it under the names "SL" and "SLC"). Will it remain Red Hat based? Will the next cern linux be ubuntu/debian based? Will Red Hat relax their rules to keep CERN (and the HEP community)? As an added kink, with the major changes from RHEL6 to RHEL7, the cost of going from SLC6 to RHEL based SLC7 becomes comparable to going from SLC6 to a ubuntu/debian based SLC? Whatever the case, there will continue to exist a linux of production quality and of free or affordable cost. -- Konstantin Olchanski Data Acquisition Systems: The Bytes Must Flow!
