There is plenty of information out there but you need to be a bit careful and considerate because some things are just outdated or way easier nowadays. - A good way to start is the Wiki maybe [1]. It seems more complete and up-to-date. Another good thing is you can always change or update sections that are not current or correct anymore. It covers the fedpkg- way of building the complete kernel package. - You already found this in the Fedora Docs: [2]. First thing that jumps into my eye is that it fails to mention that it is much easier to disable Secure Boot rather than enroll your own keys in the firmware. Nice thing about Fedora Docs: You can also update, review, and contribute there: [3]. Maybe I do that just because of that Secure Boot thing :-) - The excellent Fedora Magazine has some articles about building and testing kernels: [4] - There's also the $HOME/rpmbuild tree way (rpmdev-setuptree creates one for you). You already seen that here on the list. It is essentially the same what fedpkg and mock do, just not in a chroot'ed environment, and thus might not be the "cleanest" way to test if a build is actually working. - You asked for something to read. However, there are a couple of Fedora community videos online that explain some internals and show where people want to go with Fedora kernel work. Tremendously helpful to get a wider picture. * One from 2017, Laura Abbott hosted a discussion with a lot of insights: [5] * Something from last year: [6]. Explains what is Fedora ARK and more recent developments - If you are interested in contributing config changes, continuous testing, integrating patches, take a look at Fedora ARK (Always Ready Kernels) at [7] and esp. [8]. There's a contributors guide, too. It also shows how to use Koji to build packages (e.g., not on your local machine, for other arches). I think these links are the most useful things to read when you are interested to work with others and get changes into Fedora. In the end, the kernel is an RPM package like any other (uh, a more complicated package, though). There are a couple of resources on RPM spec files and packaging in general: [9] [10]. If you are not interested in the packaging or in the Fedora-way you have the option to go full vanilla.
