13 | <para>Finally, clean up some extra files left around from running tests:</para>

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>

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>
|

|

57 |
|
---|
58 | <para>There are also several files installed in the /usr/lib and /usr/libexec
|
---|
59 | directories with a file name extension of .la. These are "libtool archive"
|
---|
60 | files. As already said, they are only useful when linking with static
|
---|
61 | libraries. They are unneeded, and potentially harmful, when using dynamic
|
---|
62 | shared libraries, specially when using also non-autotools build systems.
|
---|
63 | To remove them, run:</para>
|
---|
64 |
|
---|
65 | <screen><userinput>find /usr/lib /usr/libexec -name \*.la -delete</userinput><userinput arch="ml_32,ml_all">
|
---|
66 | find &usr-lib-m32; -name \*.la -delete</userinput><userinput arch="ml_x32,ml_all">
|
---|
67 | find &usr-lib-mx32; -name \*.la -delete</userinput></screen>
|
---|
68 |
|
---|
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>

72 |
|
---|
73 | <para>The compiler built in <xref linkend="chapter-temporary-tools"/> and
|
---|
74 | <xref linkend="chapter-chroot-temporary-tools"/> is still partially
|
---|
75 | installed and not needed anymore. Remove it with:</para>
|
---|
76 |
|
---|
77 | <screen><userinput>find /usr -depth -name $(uname -m)-lfs-linux-gnu\* | xargs rm -rf</userinput></screen>
|
---|
78 |
|
---|
79 | <para>The <filename class="directory">/tools</filename> directory can also
|
---|
80 | be removed to further gain some space:</para>
|
---|
81 |
|
---|
82 | <screen><userinput>rm -rf /tools</userinput></screen>
|
---|
83 |
|
---|
84 | <para>Finally, remove the temporary 'tester' user account created at the
|
---|
85 | beginning of the previous chapter.</para>
|
---|
86 |

87 | <screen><userinput>userdel -r tester</userinput></screen>
