In normal world applications are written to the specification of the operating system ... In grid world seems it is the other way around ? I find the idea of "extending" SL that way completely countrary to the idea of "Red Hat Enterprise Linux compatible OS" - what SL is supposed to be in first place. But maybe other people on the list disagree with me ..
