  <title>LFS and Standards</title>

  <!--<sect2>
    <title/> -->

     <para>The structure of LFS follows Linux standards as closely as
     possible.  The primary standards are:</para>

    <itemizedlist>
      <listitem>
        <para><ulink url="http://pubs.opengroup.org/onlinepubs/9699919799/">
        POSIX.1-2008</ulink>.</para>

        <para><ulink 
        url="http://refspecs.linuxfoundation.org/FHS_3.0/fhs/index.html">
        Filesystem Hierarchy Standard (FHS) Version 3.0</ulink></para>

      </listitem>
      <listitem>
        <para><ulink url="http://refspecs.linuxfoundation.org/lsb.shtml">Linux
        Standard Base (LSB) Version 5.0 (2015)</ulink></para>

        <para>The LSB has four separate standards: Core, Desktop,
        Runtime Languages, and Imaging. In addition to generic requirements
        there are also architecture specific requirements.  There are also two
        areas for trial use: Gtk3 and Graphics.  LFS attempts to conform to the
        architectures discussed in the previous section.</para>

        <note><para>Many people do not agree with the requirements of the LSB.
        The main purpose of defining it is to ensure that proprietary software
        will be able to be installed and run properly on a compliant system.
        Since LFS is source based, the user has complete control over what
        packages are desired and many choose not to install some packages that
        are specified by the LSB.</para></note>

      </listitem>
    </itemizedlist>

    <para>Creating a complete LFS system capable of passing the LSB
    certifications tests is possible, but not without many additional packages
    that are beyond the scope of LFS.  These additional packages have
    installation instructions in BLFS. </para>
