The kernels are different too, though the only difference is a 3,4 and 5. The kernels are packed, so perhaps the number 3 is used a lot more in the kernel than the number 4, and therefore packed better. Another wild guess is that gzipping zips a bit different every time. I am not sure of this, but I have heard that some packagers (powerpacker, DMS) pack different every time. You should try something like this: #make-kpkg clean #make-kpkg --append-to-version -tao4 kernel_image install kernel note the size delete the kernel #make-kpkg clean #make-kpkg --append-to-version -tao4 kernel_image install kernel note the size delete the kernel and see if the sizes change.
