The installation of the kernel headers in chapter 5 was changed so having the
sources in a directory other than /usr/src/linux won't break the cp.

4<para><userinput>make mrproper:</userinput> This will ensure that the kernel
5tree is absolutely clean.</para>
6
7<para><userinput>yes "" | make config:</userinput> This runs make config and
8answers with the default answer to every question the config script asks
9the user (it does this by simply doing the equivalent of hitting the
10Enter key, thus accepting the default Y and N answers to the questions).
11We're not configuring the real kernel here, we just need to have some sort
12of configure file created so that we can run make dep next that will
13create a few header files in <filename>include/linux</filename>, like
14version.h, among others, that we will need to compile Glibc and other
15packages later in chroot.</para>
16
17<para><userinput>make dep:</userinput> make dep checks dependencies and sets
18up the dependencies file. We don't really care about the dependency
19checks, but what we do care about is that make dep creates those
20aforementioned files in <filename>include/linux</filename> we will be
21needing later on.</para>
22
23<para><userinput>cp -HR include/asm $LFS/usr/include</userinput>
24and <userinput>cp -HR include/linux $LFS/usr/include</userinput>:
25These commands copy the required kernel header files to
26<filename>$LFS/usr/include</filename>.</para>
27
28<para><userinput>chown -R root.root $LFS/usr/include</userinput>:
29This ensures all header files under <filename>$LFS/usr/include</filename>
30are owned by user root and group root.</para>
