olddefconfig uses defaults for new symbols but oldconfig for "old" symbols. It's the same as 'yes "" | make oldconfig'. >From "make help", silentoldconfig="Same as oldconfig, but quietly, additionally update deps". But there's so much screen output when you run them that I don't think that you can spot the difference (I couldn't when I tried a few years ago; and IIRC 'yes "" | make silentoldconfig' fails - I can't remember why).
