See the author take on the challenge that was posed to you in the previous video.
- [Voiceover] Let's look at fetching a kernel…source RPM for a disk like CentOS.…So we can use Yum Downloader…with the dash dash source option,…and the name of the package we want is Kernel.…So that took a little less than 18 seconds.…We look at the size of the source RPM,…and it's about 83 meg.…Let's install the source RPM, we don't need to be root…to install a source RPM.…It complains that we don't have the group builder…because it wants to use the group builder…as the group ID on the files, but that's OK,…we don't need that.…
We change into our home directory, RPM Build SPECS.…In the SPECS directory we see the Kernel dot Spec file,…we do a build prep with that.…That untarred it and did a few other things.…We change into the BUILD directory.…In the BUILD directory we see a sub-directory…for our kernel, we go in that directory…and have another sub-directory for Linux,…and that's the top level for the kernel source.…
Let's look at how we can fetch the Ubuntu…kernel source code using git.…So we need to know which version of Ubuntu…
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.
