In a second note about the multi-NIC, i would focus in the actual card that have the connections

That's my point, I only have one NIC (it's a desktop system) yet NM created two config files, one with ONBOOT=no and the other with ONBOOT=yes. I reinstalled the system yet again, and this time there was only one. I don't really like how NM affects the system; I think I'll disable it and edit the ifcfg file by hand (well, with a script).
