11 <title>Cleaning Up</title>
13 <para>Finally, clean up some extra files left around from running tests:</para>
15<screen><userinput>rm -rf /tmp/*</userinput></screen>
17 <para>Now log out and reenter the chroot environment with an updated
18 chroot command. From now on, use this updated chroot command any time
19 you need to reenter the chroot environment after exiting:</para>
21<screen role="nodump"><userinput>logout
23chroot "$LFS" /usr/bin/env -i \
24 HOME=/root TERM="$TERM" \
25 PS1='(lfs chroot) \u:\w\$ ' \
26 PATH=/bin:/usr/bin:/sbin:/usr/sbin \
27 /bin/bash --login</userinput></screen>
29 <para>The reason for this is that the programs in <filename
30 class="directory">/tools</filename> are no longer needed. For this reason
31 you can delete the <filename class="directory">/tools</filename>
32 directory if so desired.</para>
34 <note>
35 <para>Removing <filename class="directory">/tools</filename> will also
36 remove the temporary copies of Tcl, Expect, and DejaGNU which were used
37 for running the toolchain tests. If you need these programs later on,
38 they will need to be recompiled and re-installed. The BLFS book has
39 instructions for this (see <ulink url="&blfs-root;"/>).</para>
40 </note>
42 <para>If the virtual kernel file systems have been unmounted, either manually
43 or through a reboot, ensure that the virtual kernel file systems are mounted
44 when reentering the chroot. This process was explained in <xref
45 linkend="ch-system-bindmount"/> and <xref
46 linkend="ch-system-kernfsmount"/>.</para>
48 <para>There were several static libraries that were not suppressed earlier
49 in the chapter in order to satisfy the regression tests in several packages. These
50 libraries are from binutils, bzip2, e2fsprogs, flex, libtool, and zlib. If desired,
51 remove them now:</para>
53<screen><userinput>rm -f /usr/lib/lib{bfd,opcodes}.a
54rm -f /usr/lib/libbz2.a
55rm -f /usr/lib/lib{com_err,e2p,ext2fs,ss}.a
56rm -f /usr/lib/libltdl.a
57rm -f /usr/lib/libfl.a
58rm -f /usr/lib/libz.a</userinput></screen>
60 <para>There are also several files installed in the /usr/lib and /usr/libexec
61 directories with a file name extention of .la. These are "libtool archive"
62 files. As already said, they are only useful when linking with static
63 libraries. They are unneeded, and potentially harmful, when using dynamic
64 shared libraries, specially when using also non-autotools build systems.
65 To remove them, run:</para>
67<screen><userinput>find /usr/lib /usr/libexec -name \*.la -delete</userinput></screen>
69 <para>For more information about libtool archive files, see the <ulink
70 url="&blfs-book;/introduction/la-files.html">BLFS section "About Libtool
71 Archive (.la) files"</ulink>.</para>
73 <para>Finally, remove the temporary 'tester' usr account created at the
74 beginning of this chapter.</para>
76<screen><userinput>sed -i '/tester/d' /etc/passwd /etc/group
77rm -rf /home/tester</userinput></screen>
