13 <note>
14 <para>The commands in the remainder of this book must be performed while
15 logged in as user <systemitem class="username">root</systemitem> and no
16 longer as user <systemitem class="username">lfs</systemitem>. Also, double
17 check that <envar>$LFS</envar> is set in <systemitem
18 class="username">root</systemitem>'s environment.</para>
19 </note>

21 <para>Currently, the whole directory hierarchy in <filename
22 class="directory">$LFS</filename>
23 is owned by the user <systemitem class="username">lfs</systemitem>, a user
24 that exists only on the host system. If the directories under <filename
25 class="directory">$LFS</filename> are kept as they are, the files are
26 owned by a user ID without a corresponding account. This is dangerous because
27 a user account created later could get this same user ID and would own all
28 the files under <filename class="directory">$LFS</filename>, thus exposing
29 these files to possible malicious manipulation.</para>
30
31 <para>To address this issue, change the
32 ownership of the <filename class="directory">$LFS/*</filename> directories to
33 user <systemitem class="username">root</systemitem> by running the following
34 command:</para>
35
36<screen><userinput>chown -R root:root $LFS/{usr,lib,var,etc,bin,sbin,tools}
37case $(uname -m) in
38 x86_64) chown -R root:root $LFS/lib64 ;;
39esac</userinput></screen>
