    14   directory, <filename class="directory">/cross-tools</filename> directory, and
    15   <filename class="directory">$LFS</filename> directory are owned
    16   by the user <systemitem class="username">lfs</systemitem>,
    17   a user that exists only on the host system. For security reasons, the
    18   $LFS root directory and all of it subdirectories should be owned by
    19   <systemitem class="username">root</systemitem>. Change the ownership for $LFS and its subdirectories by running these commands:</para>

    24   <para os="b">The same issue also exists with <filename class="directory">/tools</filename> and <filename class="directory">/cross-tools</filename>. Although these directories can be deleted once the
    25   LFS system has been finished, they can be retained to build additional
    26   LFS systems. If the <filename class="directory">/tools</filename> and <filename class="directory">/cross-tools</filename>
    27   directories are kept as is, the files are owned by a user ID without a
    28   corresponding account. This is dangerous because a user account created
    29   later could get this same user ID and would own the <filename
    30   class="directory">/tools</filename> and <filename class="directory">/cross-tools</filename> directories and all the files therein,
    31   thus exposing these files to possible malicious manipulation.</para>
    32 
    33   <para os="c">To avoid this issue, add the <systemitem
    34   class="username">lfs</systemitem> user to the new LFS system later when
    35   creating the <filename>/etc/passwd</filename> file, taking care to assign
    36   it the same user and group IDs as on the host system. Alternatively,
    37   assign the contents of the <filename class="directory">/tools</filename>
    38   and <filename class="directory">/cross-tools</filename> directories to user <systemitem class="username">root</systemitem> by running
    39   the following commands:</para>
