The 5.0.0-36-generic kernel was the one I encountered with the Ubuntu 18.04.3 LTS at the time of writing this chapter. This target has kbuild generate a few header files that are further used in the setup to build the kernel. The short answer is that it's on the public kernel repository server visible at https://www.kernel.org. It will be off by default, so let's turn it on; that is, let's make it y, built into the kernel image. Here, to help you understand the nuances of selecting a valid starting point for kernel configuration, we will see three approaches to obtaining a starting point for kernel configuration that (we hope) are typical: Let's examine each of these approaches in a bit more detail. This can be achieved as follows: The lsmod(8) utility simply lists all the kernel modules currently residing in system (kernel) memory. He was programming in C and Assembly on DOS until he discovered the joys of Unix, and by around 1997, Linux! For the majority of developers like you working on a project or product, the decision has already been made – the project uses a very specific Linux kernel version. He has actively worked on several commercial/FOSS projects.
