+<para>From now on, when you exit the chroot environment and wish to reenter
+it, you should use the following modified chroot command:</para>
+
+<screen><userinput>chroot "$LFS" /usr/bin/env -i \
+    HOME=/root TERM="$TERM" PS1='\u:\w\$ ' \
+    PATH=/bin:/usr/bin:/sbin:/usr/sbin \
+    /bin/bash --login</userinput></screen>
+
+<para>The reason for this is that, since the programs in <filename 
+class="directory">/tools</filename> are no longer needed, you may want to
+delete the whole directory and regain the space. Before actually deleting the
+directory, exit from chroot and reenter it with the above command. Also, before
+removing <filename class="directory">/tools</filename>, you may want to tar it
+up and store it in a safe place, in case you want to build another LFS system
+soon.</para>
+
+<note><para>Removing <filename class="directory">/tools</filename> will also
+remove the temporary copies of Tcl, Expect and DejaGnu, which were used for
+running the toolchain tests. If you want to use these programs later on, you
+will need to recompile and re-install them. The installation instructions are
+the same as in <xref linkend="chapter-temporary-tools"/>, apart from changing
+the prefix from <emphasis>/tools</emphasis> to <emphasis>/usr</emphasis>. The
+BLFS book discusses a slightly different approach to installing Tcl, see 
+<ulink url="&blfs-root;"/>.</para></note>
+
+<para>You may also want to move the packages and patches stored in <filename 
+class="directory">/sources</filename> to a more usual location, such as
+<filename class="directory">/usr/src/packages</filename>, and remove the
+directory -- or simply delete the whole directory if you've burned its contents
+on a CD).</para>
