SLC6: Scientific Linux CERN 6

What will be Scientific Linux CERN 6 (SLC6) ?

Scientific Linux CERN 6 will be 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 6.0 (SLC6.0) TEST1

A TEST version of future SLC6 is available since 29.11.2010 for installs via the PXE network boot at CERN from the 'Expert Operating System Install Menu' / 'SLC 6 PREVIEW/TEST Install Menu'

Please note that this is a pre-release version NOT suitable for production purposes and possibly affected by numerous problems.

Since the SLC6 version is not supported yet please note that we ( do not guarantee timely updates (including security ones) nor CERN helpdesk offers support for it. If you would like to participate in discussions about future SLC6 please join mailing list.

Known problems
