    <title>Installation of Linux-Libc-Headers</title>

    <para os="a">For years it has been common practice to use <quote>raw</quote>
    kernel headers (straight from a kernel tarball) in <filename
    class="directory">/usr/include</filename>, but over the last few
    years, the kernel developers have taken a strong stance that this
    should not be done. This gave birth to the Linux-Libc-Headers Project,
    which was designed to maintain an API stable version of the Linux
    headers.</para>

    <para os="b">Install the header files:</para>

<screen><userinput>cp -R include/asm-i386 /usr/include/asm
cp -R include/linux /usr/include
cp -R include/mtd /usr/include
cp -R include/sound /usr/include
cp -R include/scsi /usr/include</userinput></screen>

    <para os="c">Ensure that all the headers are owned by
    <systemitem class="username">root</systemitem>:</para>

<screen os="d"><userinput>chown -R root:root /usr/include/{asm,linux,mtd,sound,scsi}</userinput></screen>

    <para os="e">Make sure the users can read the headers:</para>
