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" \
22 PS1='(lfs chroot) \u:\w\$ ' \
23 PATH=/bin:/usr/bin:/sbin:/usr/sbin \
24 /bin/bash --login</userinput></screen>
25
26 <para>The reason for this is that the programs in <filename
27 class="directory">/tools</filename> are no longer needed. Since they are no
28 longer needed you can delete the <filename class="directory">/tools</filename>
29 directory if so desired.</para>
30
31 <note>
32 <para>Removing <filename class="directory">/tools</filename> will also
33 remove the temporary copies of Tcl, Expect, and DejaGNU which were used
34 for running the toolchain tests. If you need these programs later on,
35 they will need to be recompiled and re-installed. The BLFS book has
36 instructions for this (see <ulink url="&blfs-root;"/>).</para>
37 </note>
38
39 <para>If the virtual kernel file systems have been unmounted, either manually
40 or through a reboot, ensure that the virtual kernel file systems are mounted
41 when reentering the chroot. This process was explained in <xref
42 linkend="ch-system-bindmount"/> and <xref
43 linkend="ch-system-kernfsmount"/>.</para>
44
45 <para>There were several static libraries that were not suppressed earlier
46 in the chapter in order to satisfy the regression tests in several packages. These
47 libraries are from binutils, bzip2, e2fsprogs, flex, libtool, and zlib. If desired,
48 remove them now:</para>
49
50<screen><userinput>rm -f /usr/lib/lib{bfd,opcodes}.a
51rm -f /usr/lib/libbz2.a
52rm -f /usr/lib/lib{com_err,e2p,ext2fs,ss}.a
53rm -f /usr/lib/libltdl.a
54rm -f /usr/lib/libfl.a
55rm -f /usr/lib/libfl_pic.a
56rm -f /usr/lib/libz.a</userinput></screen>
57
58 <para>There are also several files installed in the /usr/lib and /usr/libexec
59 directories with a file name extention of .la. These are "libtool archive"
60 files and generally unneeded on a linux system. None of these are necessary
61 at this point. To remove them, run:</para>
62
63<screen><userinput>find /usr/lib /usr/libexec -name \*.la -delete</userinput></screen>
64
65 <para>For more information about libtool archive files, see the <ulink
66 url="&blfs-book;/introduction/la-files.html">BLFS section "About Libtool
67 Archive (.la) files"</ulink>.</para>
