|

| 10 | way this book does it, read the <filename>README</filename> that comes

| [2bdc67d] | 11 | with the kernel source tree, and find out what the other options are.</para>

| [ce3379d4] | 13 | <para>Something you could do, is take the <filename>.config</filename>
|

| 14 | file from your host distribution's kernel source tree and copy it to

| 15 | <filename class="directory">$LFS/usr/src/linux</filename>.
|
|---|
| [01067384] | 16 | This way you don't have to configure the entire kernel from scratch and
|
|---|
| 17 | can use your current values. If you choose to do this, first run the
|
|---|
| [ce3379d4] | 18 | <userinput>make mrproper</userinput> command below, then copy the
|
|---|
| 19 | <filename>.config</filename> file over, then run
|

| 20 | <userinput>make menuconfig</userinput> followed by the rest of the commands

| 21 | (<userinput>make oldconfig</userinput> may be better in some situations.
