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 class="directory">/tools</filename> directory and all the files therein,
26 thus exposing these files to possible malicious manipulation.</para>
