Debian Kernel Building Mini-HOWTO
This is intended to be a quick and dirty guide to building your own kernel packages for Debian. For more information, see the links at the end of the article.
1. Install the packages 'kernel-package' and 'fakeroot'.
2. Get a Linux kernel tarball, either from kernel.org or from a Debian package (kernel-source-x.x.xx).
3. Uncompress the tarball to a place of your choice (Debian kernel source packages end up in /usr/src)
4. cd into the kernel source directory
5. Configure your kernel (I prefer 'make menuconfig' - note that for menuconfig you will need libncurses5-dev)
6. Execute this command: fakeroot make-kpkg kernel_image
7. You will have a kernel deb in the parent directory of your kernel source now (e.g. /usr/src). Install it using dpkg (dpkg -i file.deb)
If you use grub, here is what you need to do to get your menu.lst automatically updated.
Create a file /etc/kernel-img.conf and add the following lines:
postinst_hook = /sbin/update-grub
postrm_hook = /sbin/update-grub
do_bootloader = no
This will ensure update-grub is ran upon installation of any kernel packages, self-created or Debian-created.
For many more details about building kernels and Debian, see the following sources:
