<para>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 <filename>README</filename> that comes
|
|
with the kernel source tree, and find out what the other options are.</para>
|
|
|
|
<para>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 <filename>README</filename> file for more details when to use make
|
|
oldconfig).</para>

<para>The following commands are run to build the kernel:</para>
