13 <para>Finally, clean up some extra files left around from running tests:</para>
14
15<screen><userinput>rm -rf /tmp/*</userinput></screen>
16
17 <para>From now on, when reentering the chroot environment after
18 exiting, use the following modified chroot command:</para>
19
20<screen role="nodump"><userinput>chroot "$LFS" /usr/bin/env -i \
21 HOME=/root TERM="$TERM" PS1='\u:\w\$ ' \
22 PATH=/bin:/usr/bin:/sbin:/usr/sbin \
23 /bin/bash --login</userinput></screen>
24
25 <para>The reason for this is that the programs in <filename
26 class="directory">/tools</filename> are no longer needed. Since they are no
27 longer needed you can delete the <filename class="directory">/tools</filename>
28 directory if so desired.</para>
29
30 <note>
31 <para>Removing <filename class="directory">/tools</filename> will also
32 remove the temporary copies of Tcl, Expect, and DejaGNU which were used
33 for running the toolchain tests. If you need these programs later on,
34 they will need to be recompiled and re-installed. The BLFS book has
35 instructions for this (see <ulink url="&blfs-root;"/>).</para>
36 </note>
37
38 <para>If the virtual kernel file systems have been unmounted, either manually
39 or through a reboot, ensure that the virtual kernel file systems are mounted
40 when reentering the chroot. This process was explained in <xref
41 linkend="ch-system-bindmount"/> and <xref
42 linkend="ch-system-kernfsmount"/>.</para>
43
44 <para>Finally, there were several static libraries that were not supressed earlier
45 in the chapter in order to satisfy the regression tests in several packages. These
46 libraries are from binutils, bzip2, e2fsprogs, flex, libtool, and zlib. If desired,
47 remove them now:</para>
