All, I've read a lot of reviews online and a recent pitch at CERN (before presentation!) Now that Redhat has bought Centos... https://www.google.com/#q=rhel+centos+cern+pdf 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
