| 12 | <para>Something you could do, is take the .config file from your host

|
---|
| 14 | This way you don't have to configure the entire kernel from scratch and
|
---|
| 15 | can use your current values. If you choose to do this, first run the
|
---|
| 16 | make mrproper command below, then copy the .config file over, then run
|
---|
[2bdc67d] | 17 | make menuconfig (make oldconfig may be better in some situations. See
