(And others - for > example, tuning(7) still implicitly recommends a 128 MB root file system). well.. I dont think that 60% increase of size when you are optimizing for size is normal. I even think its a "bug" in that sense that something wrong is set somewhere which causes this. I certainly dont believe this is normal
