    <para>The Tar package provides the ability to create tar archives as well
    as perform various other kinds of archive manipulation.  Tar can be used on
    previously created archives to extract files, to store additional files, or
    to update or list files which were already stored. </para>

          <para>This forces the test for <function>mknod</function> to be run
          as <systemitem class="username">root</systemitem>.
          It is generally considered dangerous to run this test as
          the <systemitem class="username">root</systemitem> user, but as it
          is being run on a system that has only been
          partially built, overriding it is OK.</para>

    <para>One test, capabilities: binary store/restore, is known to fail if it is
    run because LFS lacks selinux, but will be skipped if the host kernel does
    not support extended attributes or security labels on the filesystem
    used for building LFS.</para>
