Any reason its so huge compared to the other ones?Self built kernel with debug + unstripped modules perhaps? Not sure what the behaviour of RH''s mkinitrd (drakut?) is but if it includes a large selection of modules, all of which have full debug then it could quickly add up to those sorts of sizes. Ian.
