Even though we label the source code, we would like to make sure that we are all building the same kernel by running md5sum on the resulting binary. Right now, this is not possible because the kernel includes a timestamp and a build number on the binary. What are this timestamps used for? Can we just remove them? Is there any other thing that may lead to different binaries? (we are using the exact toolchains and build machines, so we can assume that the same executable is generated if the input source is the same). Please, cc me in your replies because I'm not subscribed to the list. Thanks for your time, Ed
