Building the kernel involves a few steps: configuring it and compiling it. There are a few ways to configure the kernel. If you don't like the way this book does it, read the README that comes with the kernel source tree, and find out what the other options are.
Something you could do, is take the .config file from your host distribution's kernel source tree and copy it to $LFS/usr/src/linux. This way you don't have to configure the entire kernel from scratch and can use your current values. If you choose to do this, first run the make mrproper command below, then copy the .config file over, then run make menuconfig (make oldconfig may be better in some situations. See the README file for more details when to use make oldconfig).
The following commands are run to build the kernel:
cd /usr/src/linux && make mrproper && make menuconfig && make dep && make bzImage && make modules && make modules_install && cp arch/i386/boot/bzImage /boot/lfskernel && cp System.map /boot |
Note: the arch/i386/boot/bzImage path may vary on different platforms.
