- <title>Changing Ownership</title>
-
- <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>$LFS</envar> is set in <systemitem
- class="username">root</systemitem>'s environment.</para>
- </note>
-
- <para>Currently, the <filename class="directory">$LFS/tools</filename> directory
- is owned by the user <systemitem class="username">lfs</systemitem>, a user
- that exists only on the host system. If the <filename
- class="directory">$LFS/tools</filename> directory is kept as is, the files are
- owned by a user ID without a corresponding account. This is dangerous because
- a user account created later could get this same user ID and would own the
- <filename class="directory">$LFS/tools</filename> directory and all the files
- therein, 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/tools</filename> directory to
- user <systemitem class="username">root</systemitem> by running the following
- command:</para>
-
-<screen><userinput>chown -R root:root $LFS/tools</userinput></screen>
-
- <para>Although the <filename class="directory">$LFS/tools</filename> directory
- can be deleted once the LFS system has been finished, it can be retained to build
- additional LFS systems <emphasis>of the same book version</emphasis>. How best
- to backup <filename class="directory">$LFS/tools</filename> is a matter of
- personal preference.</para>
-
- <caution>
- <para>If you intend to keep the temporary tools for use in building future LFS
- systems, <emphasis>now</emphasis> is the time to back them up. Subsequent
- commands in chapter 6 will alter the tools currently in place, rendering them
- useless for future builds.</para>
- </caution>
