Finally, clean up some extra files left around from running tests:
|
|
</p>
|
|
<pre class="userinput">
|
|
<kbd class="command">rm -rf /tmp/*</kbd>
|
|
</pre>
|
|
<p>
|
|
From now on, when reentering the chroot environment after exiting,
|
|
use the following modified chroot command:
|
|
</p>
|
|
<pre class="userinput">
|
|
<kbd class="command">chroot "$LFS" /usr/bin/env -i \
|
|
HOME=/root TERM="$TERM" PS1='\u:\w\$ ' \
|
|
PATH=/bin:/usr/bin:/sbin:/usr/sbin \
|
|
/bin/bash --login</kbd>
|
|
</pre>
|
|
<p>
|
|
The reason for this is that the programs in <code class=
|
|
"filename">/tools</code> are no longer needed. Since they are no
|
|
longer needed you can delete the <code class="filename">/tools</code>
|
|
directory if so desired.
|
|
</p>
|
|
<div class="admon note">
|
|
<img alt="[Note]" src="../images/note.png" />
|
|
<h3>
|
|
Note
|
|
</h3>
|
|
<p>
|
|
Removing <code class="filename">/tools</code> will also remove the
|
|
temporary copies of Tcl, Expect, and DejaGNU which were used for
|
|
running the toolchain tests. If you need these programs later on,
|
|
they will need to be recompiled and re-installed. The BLFS book has
|
|
instructions for this (see <a class="ulink" href=
|
|
"http://www.linuxfromscratch.org/blfs/">http://www.linuxfromscratch.org/blfs/</a>).
|
|
</p>
|
|
</div>
|
|
<pre class="userinput">
|
|
<kbd class="command">rm -rf /tools</kbd>
|
|
</pre>

<p>

|
If the virtual kernel file systems have been unmounted, either
|
|
manually or through a reboot, ensure that the virtual kernel file
|
|
systems are mounted when reentering the chroot. This process was
|
|
explained in <a class="xref" href="kernfs.html#ch-system-bindmount"
|
|
title="6.2.2. Mounting and Populating /dev">Section 6.2.2,
