-<para>Exit from chroot:</para>
+<para>If the intended user is not a programmer and does not plan to do
+any debugging on the system software, the system size can be decreased
+by about 200 MB by removing the debugging symbols from binaries and
+libraries. This causes no inconvenience other than not being able to
+debug the software fully anymore.</para>
+
+<para>Most people who use the command mentioned below do not
+experience any difficulties. However, it is easy to make a typo and
+render the new system unusable, so before running the
+<command>strip</command> command, it is a good idea to make a
+backup of the current situation.</para>
+
+<para>Before performing the stripping, take special care to ensure that
+none of the binaries that are about to be stripped are running. If
+unsure whether the user entered chroot with the command given in
+<xref linkend="ch-system-chroot" role=","/> first exit from
+chroot:</para>
<screen><userinput>logout</userinput></screen>
-<para>Reenter with:</para>
+<para>Then reenter it with:</para>
<screen><userinput>chroot $LFS /tools/bin/env -i \
HOME=/root TERM=$TERM PS1='\u:\w\$ ' \
PATH=/bin:/usr/bin:/sbin:/usr/sbin \
/tools/bin/bash --login</userinput></screen>
-<para>Strip the binaries and libraries:</para>
+<para>Now the binaries and libraries can be safely stripped:</para>
<screen><userinput>/tools/bin/find /{,usr/}{bin,lib,sbin} -type f \
-exec /tools/bin/strip --strip-debug '{}' ';'</userinput></screen>
+<para>A large number of files will be reported as having their file
+format not recognized. These warnings can be safely ignored. These
+warnings indicate that those files are scripts instead of
+binaries.</para>
+
+<para>If disk space is very tight, the
+<parameter>--strip-all</parameter> option can be used on the binaries
+in <filename class="directory">/{,usr/}{bin,sbin}</filename> to gain
+several more megabytes. Do not use this option on libraries&mdash;they will
+be destroyed.</para>
