What is Scientific Linux CERN 6 (SLC6) ?

Scientific Linux CERN 6 is a Linux distribution build within the framework of Scientific Linux which in turn is rebuilt from the freely available Red Hat Enterprise Linux 6 (Server) product sources under terms and conditions of the Red Hat EULA. Scientific Linux CERN is built to integrate into the CERN computing environment but it is not a site-specific product: all CERN site customizations are optional and can be deactivated for external users.

Scientific Linux CERN 6 Support Lifetime

Since SLC/SL are based on sources of Red Hat Enterprise Linux 6 (RHEL6) sources the support lifetime cannot be longer than the one proposed by Red Hat. Due to CERN environment constraints (available manpower, hardware purchases procedures .. etc.) Scientific Linux CERN 6 Lifetime may be actually shorter than RHEL6 one, subject to Linux Certification Committee decision.
At present following End of Support dates are foreseen: In addition to the above dates please note that from Q2 2016 we will not accept any request for new features. From Q2 2017 only security updates will be provided (except for CERN-specific software included). (please see: RHEL6 product support life cycle)
