Kevin provides some challenges wherein you fetch Linux kernel source code from kernel.org and from a Linux distribution, unpack the source code, peruse the source code, and search & read kernel documentaiton.
- [Voiceover] In your exercise files,…you should find the document Chapter 4 Challenges.pdf…with the questions for working with kernel source code…where we fetch the kernel, and we do some…checking of some cool stuff.…Now how long this set of challenges takes…really depends on your download speed.…In particular, cloning the Ubuntu source for the kernel…might take a while.…It took me 25 minutes to download it on my system,…so the total time could well be more than 30 minutes,…but the time of you typing and doing stuff…is about 30 minutes plus the additional time for downloads.…

5/23/2016We 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.
