Section 7. Configuring the Kernel is incorrect on kernel installation, one should not cp in the image on x86/amd64 but instead use "make install" which works with both lilo and grub. Reproducible: Always Steps to Reproduce: 1. 2. 3.
grub/lilo isn't installed in that fase of the installation, and "make install" does about the same things as we do (like copy'ing the image over).
Do concider that when people read that they must cp the kernel over by hand, they will do that every kernel compile. "make install" is by far easier to work with since it cp's the files over and symlinks them to /boot/vmlinuz /boot/System.map. Also "make install" is just easier to remember. Atleast a side is worthy for "make install" since the kernel maintainers thought it necessary to include in the kernel makefile.
Since grub/lilo isn't available at that time, it's hardly possible to do this either way. Also, running "make install" might be easier but most people should verify the made changes anyway. There's nothing wrong with the current approach. I'll add a note that subsequently, users can use "make install".
Note's added to the bootloader chapter.
