13    <para>Currently, the <filename class="directory">/tools</filename>
14    and <filename class="directory">/cross-tools</filename> directories
15    are owned by the user <emphasis>lfs</emphasis>, a user that
16    exists only on the host system. Although the <filename
17    class="directory">/tools</filename> and <filename
18    class="directory">/cross-tools</filename> directories can be deleted
19    once the LFS system has been finished, they can be retained to build
20    additional LFS systems. If the <filename class="directory">/tools</filename>
21    and <filename class="directory">/cross-tools</filename> directories are
22    kept as is, the files are owned by a user ID without a corresponding
23    account. This is dangerous because a user account created later could
24    get this same user ID and would own the <filename
25    lass="directory">/tools</filename> directory and all the files therein,
26    thus exposing these files to possible malicious manipulation.</para>
