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=/usr/bin:/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 are also several files installed in the /usr/lib and /usr/libexec
40 directories with a file name extension of .la. These are "libtool archive"
41 files. As already said, they are only useful when linking with static
42 libraries. They are unneeded, and potentially harmful, when using dynamic
43 shared libraries, specially when using also non-autotools build systems.
44 To remove them, run:</para>
45
46<screen><userinput>find /usr/lib /usr/libexec -name \*.la -delete</userinput><userinput arch="ml_32,ml_all">
47find /usr/lib32 -name \*.la -delete</userinput><userinput arch="ml_x32,ml_all">
48find /usr/libx32 -name \*.la -delete</userinput></screen>
49
50 <para>For more information about libtool archive files, see the <ulink
51 url="&blfs-book;/introduction/la-files.html">BLFS section "About Libtool
52 Archive (.la) files"</ulink>.</para>
53
54 <para>The compiler built in <xref linkend="chapter-temporary-tools"/> and
55 <xref linkend="chapter-chroot-temporary-tools"/> is still partially
56 installed and not needed anymore. Remove it with:</para>
57
58<screen><userinput>find /usr -depth -name $(uname -m)-lfs-linux-gnu\* | xargs rm -rf</userinput></screen>
59
60 <para>Finally, remove the temporary 'tester' user account created at the
61 beginning of the previous chapter.</para>
62
63<screen><userinput>userdel -r tester</userinput></screen>
64</sect1>
