Remember that CERN turns the dates around to show day first.

The presentation you linked to dated 12/02/14 was given in February 12 2014.  Those slides are pretty old.

But CERN did in fact go on to announce they would base on CentOS for version 7.

Subject: Q&A: Centos vs SL

All, I've read a lot of reviews online

and a recent pitch at CERN (before presentation!)

Now that Redhat has bought Centos...

http://linux.web.cern.ch/linux/docs/GDB%2020140212%20-%20Future%20of%20Scientific%20Linux%20in%20light%20of%20recent%20CentOS%20project%20changes..pdf

So I'm looking to head towards Centos and wondering how easy it
will be to install GEANT...and if I should wait. I am not a power
user.

?

Thanks
