I looked at some web pages on the debian way of compiling kernels etc. My general strategy is as follows: 1. Download the latest stable kernel from the kernel archives; this is 4.14.15 - I have done this. 2. Use the tar xf /usr/src/linux-source-4.14.15.tar.xz command to unpack the kernel source file. 3. cd to the directory where the kernel source lives 4. Reuse the config file from the 4.14.15 rc8 kernel I already have installed e.g. cp /boot/config-3.16.0-4-amd64 ~/kernel/linux-source-3.16/.config 5. run make menuconfig (I do this in gentoo) I will make sure libncurses5-dev (or does it need to be newer?) is installed to configure it using the recycled config file from 4 above. 6. Run make-kpkg clean. 7. Then run fakeroot make-kpkg --initrd --revision=1.0.custom kernel_image. 8. Then install the kernel as follows: dpkg -i ../linux-image-4.14.15-subarchitecture_1.0.custom_i386.deb. 9. Reboot and look for new kernel in grub menu and log in. 10. Run the patch checker to see that KPTI and retpoline patched are turned on properly. Please critique the above list. I am going to read more documentation and improve it before going ahead with this.
