When compiling and installing a custom kernel for a Debian based Linux system, wouldn’t it be nice if your new Kernel was installable (or removable) trough the Debian package manager? And wouldn’t it even be nicer if that package also created the GRUB menu entries for that new Kernel? And maybe you need a „initrd“ image as well?
All the above (and more) could easily be achieved by using a tool called „make-kpgk“. The usage of this tool, I will try to describe in the following steps.
Step 1: install „make-kpgk“
On a Debian based system just „apt-get“ like this:
apt-get install kernel-package
Step 2: get some Kernel sources
Download the Kernel sources from kernel.org, extract them to a directory of your choice.
Step 3: configure your Kernel
Configure your custom Kernel as usual. For example by using „menuconfig“:
Step 4: Compile your Kernel
Instead of using something like „make bzImage modules“, we will use „make-kpkg“. To generate a Kernel with modules and „initrd“ image, we issue the following command:
make-kpkg --initrd --bzimage kernel-image
This will produce a Debian package (e.g. linux-image-2.6.34_2.6.34-10.00.Custom_i386.deb).
Step 4: install your Kernel
The Kernel could be installed by using „dpkg“:
dpkg -i linux-image-2.6.34_2.6.34-10.00.Custom_i386.deb
