Ah ah, the demo effect... just after I said I did not have much issues with repos... ^_^ A collegue installed some packages (for perconna) and since then a server insists on replacing 2 base packages with 2 rfx packages, even when I gave a lower priority to rfx...

I suspect it might be due to the new fedora release? Doesn't priority also blocks obsoleted/obsoleting packages...? I did a clean all... Thx, JD
