| 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 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></screen>
|

| 48 | <para>For more information about libtool archive files, see the <ulink

|

| 50 | Archive (.la) files"</ulink>.</para>

|

| 52 | <para>The compiler built in <xref linkend="chapter-temporary-tools"/> and
|
|---|
| 53 | <xref linkend="chapter-chroot-temporary-tools"/> is still partially
|
|---|
| 54 | installed and not needed anymore. Remove it with:</para>
|

| 55 |
|

| 56 | <screen><userinput>find /usr -depth -name $(uname -m)-lfs-linux-gnu\* | xargs rm -rf</userinput></screen>
|
|---|
| 57 |
|
|---|
| 58 | <para>Finally, remove the temporary 'tester' user account created at the
|
|---|
| 59 | beginning of the previous chapter.</para>
