Exercise

Following pretty much exactly the steps you’ve learned in this chapter, I’d like you to now do the same for some other kernel, say, the 6.0.y Linux kernel, where y is the highest number (as of this writing, it’s 19)! Of course, if you wish, feel free to work on any other kernel:

1. Navigate to https://mirrors.edge.kernel.org/pub/linux/kernel/v6.x/ and look up the 6.0.y releases.
2. Download the latest v6.0.y Linux kernel source tree.
3. Extract it to disk.
4. Configure the kernel (begin by using the localmodconfig approach, then tweak the kernel config as required. As an additional exercise, you could run the streamline_config.pl script as well).
5. Show the “delta” – the differences between the original and the new kernel config file (tip: use the kernel’s diffconfig script to do so).
