    <note><para>If you installed LFS from SVN-20120719, LFS-7.2, or later,
    use <xref linkend='udev-extras'/> instead of this page.</para></note>

    <para><application>Udev</application> was indeed installed in LFS and there
    is no reason to reinstall it unless you are going to install a package such
    as <application>UPower</application>. This installation of
    <application>Udev</application> enables extra features which includes
    <application>gudev</application>, a requirement for
    <application>UPower</application> and optionally used by other
    packages.</para>

    <para>Unlike any other package in the BLFS book, there is no set version
    of <application>Udev</application> specified to download. Several version
    updates to LFS and none to BLFS means there are probably many different
    versions of <application>Udev</application> on the platforms that BLFS is
    being built upon. Therefore, you should download and use the version of
    <application>Udev</application> your computer currently uses. The BLFS
    team has no experience updating (or reverting to an older version) the
    <application>Udev</application> package <quote>on the fly.</quote> To
    discover the version of <application>Udev</application> your computer
    currently uses, issue <command>/sbin/udevadm --version</command>.</para>

    <para>You should look at the LFS instructions for the version you used, to
    check that you are using the correct testfiles (for some versions, this was a
    separate tarball, extracted in the udev directory with --strip-components=1)
    and to compare the configure options you are about to use against those which
    you used to build the version you are running (sometimes, the options change).
