28 <para os="a">For years it has been common practice to use
29 <quote>raw</quote> kernel headers (straight from a kernel tarball) in
30 <filename class="directory">/usr/include</filename>, but over the last few
31 years, the kernel developers have taken a strong stance that this
32 should not be done. This gave birth to the Linux-Libc-Headers Project,
33 which was designed to maintain an API stable version of the Linux
34 headers. Recently this project stopped producing updates, so the Cross-LFS
35 team started development on our own project to sanitize the headers.</para>
