In this 30 minute challenge, perform hands-on activities with the Linux kernel with respect to hardware, system calls, kernel messages, the proc filesystem and the sysfs filesystem.
- [Voiceover] So let's look at some challenges.…In your exercise files you'll find the challenge questions…and your Chapter 1 Challenges.pdf document.…We're going to use what you learned so far…to find out even more about the kernel and system calls.…These challenges should take you about 30 minutes or so.…
We survey the Linux kernel specification, boot process, and loadable kernel modules. You will practice techniques such as downloading and searching Linux kernel source code and configuring a Linux kernel from scratch. Challenge and solution videos at the end of almost every chapter allow you to test your new Linux skills along the way.
