11 <title>Cleaning Up</title>
12
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>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>
20
21<screen role="nodump"><userinput>logout
22
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>
28
29 <para>Here the <parameter>+h</parameter> option is not used anymore, since
30 all the previous programs have been replaced: hashing is therefore
31 possible.</para>
32
33 <para>If the virtual kernel file systems have been unmounted, either manually
34 or through a reboot, ensure that the virtual kernel file systems are mounted
35 when reentering the chroot. This process was explained in <xref
36 linkend="ch-tools-bindmount"/> and <xref
37 linkend="ch-tools-kernfsmount"/>.</para>
38
39 <para>There were several static libraries that were not suppressed earlier
40 in the chapter in order to satisfy the regression tests in several packages. These
41 libraries are from binutils, bzip2, e2fsprogs, flex, libtool, and zlib. If desired,
42 remove them now:</para>
43
44<screen><userinput>rm -f /usr/lib/lib{bfd,opcodes}.a
45rm -f /usr/lib/libctf{,-nobfd}.a
46rm -f /usr/lib/libbz2.a
47rm -f /usr/lib/lib{com_err,e2p,ext2fs,ss}.a
48rm -f /usr/lib/libltdl.a
49rm -f /usr/lib/libfl.a
50rm -f /usr/lib/libz.a</userinput></screen>
51
52 <para>There are also several files installed in the /usr/lib and /usr/libexec
53 directories with a file name extention of .la. These are "libtool archive"
54 files. As already said, they are only useful when linking with static
55 libraries. They are unneeded, and potentially harmful, when using dynamic
56 shared libraries, specially when using also non-autotools build systems.
57 To remove them, run:</para>
58
59<screen><userinput>find /usr/lib /usr/libexec -name \*.la -delete</userinput></screen>
60
61 <para>For more information about libtool archive files, see the <ulink
62 url="&blfs-book;/introduction/la-files.html">BLFS section "About Libtool
63 Archive (.la) files"</ulink>.</para>
64
65 <para>The compiler built in <xref linkend="chapter-temporary-tools"/> and
66 <xref linkend="chapter-chroot-temporary-tools"/> is still partially
67 installed, and not needed anymore. Remove it with:</para>
68
69<screen><userinput>find /usr -depth -name $(uname -m)-lfs-linux-gnu\* | xargs rm -rf</userinput></screen>
70
71 <para>The <filename class="directory">/tools</filename> directory can also
72 be removed to further gain some place:</para>
73
74<screen><userinput>rm -rf /tools</userinput></screen>
75
76 <para>Finally, remove the temporary 'tester' user account created at the
77 beginning of the previous chapter.</para>
78
79<screen><userinput>userdel -r tester</userinput></screen>
80</sect1>
