Find the kernel command line documentation and use a wide variety of kernel boot options.
- [Voiceover] Let's talk more about booting.…In particular, let's talk more…about kernel command-line parameters.…So GRUB passes the parameters to the Linux Kernel.…And the kernel processes those command-line arguments.…And fortunately, the kernel just ignores…any that are unrecognized…so you can put some extra stuff up there…for say scripts to look at later…and sometimes that's kinda handy.…So some user space stuff can look at those options.…If you wanna see,…you can use dmesg to look…at the kernel command line,…or the kernel actually reports it…in proc/cmdline.…
If you look in the kernel source tree,…in the documentation directory,…my favorite directory in the kernel source,…there is a little text file…that documents a great number…of the kernel parameters.…And you'll see that there's like 500…of em there.…All kinds of obscure things.…Some of em are architecture dependent.…Many of them are for particular drivers,…but it's fairly common that…if you have a situation with your kernel…where it's acting unlike the way…
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.
