<para>If you are not a programmer and don't plan to do any debugging on your
|
|
system software, you can shrink your system 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 any more.</para>
|
|
|
|
<para>Most people who use the command mentioned below don't experience any
|
|
problems. But it is easy to make a typo and render your new system unusable, so
|
|
before running the strip command it is probably a good idea to make a backup of
|
|
the current situation.</para>
|
|
|
|
<para>If you are going to perform the stripping, special care is needed to
|
|
ensure you're not running any of the binaries that are about to be stripped.
|
|
If you're not sure whether you entered chroot with the command given in
|
|
<xref linkend="ch-system-chroot"/>, then first exit from chroot:</para>
|
|
|
|
<screen><userinput>logout</userinput></screen>
|
|
|
|
<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>Now you can safely strip the binaries and libraries:</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, they just mean that those
|
|
files are scripts instead of binaries, no harm is done.</para>
|
|
|
|
<para>If you are really tight on disk space, you may want to use
|
|
<parameter>--strip-all</parameter> on the binaries in
|
|
<filename class="directory">/{,usr/}{bin,sbin}</filename> to gain several more megabytes. But do
|
|
<emphasis>not</emphasis> use this option on libraries: they would be
|
|
destroyed.</para>
