<title>Installation of Linux API Headers</title>
<para>The Linux kernel needs to expose an Application Programming Interface
(API) for the system's C library (Glibc in LFS) to use. This is done
by way of sanitizing various C header files that are shipped in the Linux
kernel source tarball.</para>
<para>Make sure there are no stale files and dependencies lying around
from previous activity:</para>
<screen><userinput remap="pre">make mrproper</userinput></screen>
<para>Now extract the user-visible kernel headers from the source.
The recommended make target <quote>headers_install</quote> cannot be
used, because it requires <application>rsync</application>, which is
not available in <filename class="directory">/tools</filename>. The
headers are first placed in <filename class="directory">./usr</filename>,
then some files used by the kernel developers are removed, then
the files are copied to their final location.</para>
