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> |
