Hi to all, Here at ESA there is a group dedicated for certifying OS and SW, but, for some reason they still haven't stated, they don't trust Scientific Linux (up to now...i'm working for making it possible): in this optical, which are the supported OSs (but SL and RH7.3)? Has anyone ever installed LCG (2.4.0) on a RedHat Enterprise Edition?
