On a typical Fedora system, boot also depends on kernel modules, an initramfs assembled for the correct release, and a boot entry pointing to those artifacts. A mismatch can leave a perfectly compiled kernel unable to mount its root filesystem.</p> <p>This matters when using the upstream source from kernel.org rather than Fedora&rsquo;s kernel RPMs. Fedora&rsquo;s package installation normally coordinates several boot artifacts. A manual upstream build leaves that coordination to the administrator. The example below assumes an ordinary x86_64 Fedora installation managed with GRUB and <code>grubby</code>, not an rpm-ostree-based desktop.</p>
