+
+ <note>
+ <para>The commands in the remainder of this book must be performed while
+ logged in as user <systemitem class="username">root</systemitem> and no
+ longer as user <systemitem class="username">lfs</systemitem>. Also, double
+ check that <envar>$LFS</envar> is set in <systemitem
+ class="username">root</systemitem>'s environment.</para>
+ </note>
+
+ <para>Currently, the whole directory hierarchy in <filename
+ class="directory">$LFS</filename>
+ is owned by the user <systemitem class="username">lfs</systemitem>, a user
+ that exists only on the host system. If the directories under <filename
+ class="directory">$LFS</filename> are kept as they are, the files are
+ owned by a user ID without a corresponding account. This is dangerous because
+ a user account created later could get this same user ID and would own all
+ the files under <filename class="directory">$LFS</filename>, thus exposing
+ these files to possible malicious manipulation.</para>
+
+ <para>To avoid this issue, you could add the <systemitem
+ class="username">lfs</systemitem> user to the new LFS system later when
+ creating the <filename>/etc/passwd</filename> file, taking care to assign it
+ the same user and group IDs as on the host system. Better yet, change the
+ ownership of the <filename class="directory">$LFS/*</filename> directories to
+ user <systemitem class="username">root</systemitem> by running the following
+ command:</para>
+
+<screen><userinput>chown -R root:root
$LFS/{usr,lib,var,etc,bin,sbin,lib64,tools}</userinput></screen>
