<title>Stripping</title>
<para>The steps in this section are optional, but if the LFS partition is
rather small, it is beneficial to learn that unnecessary items can be removed.
The executables and libraries built so far contain about 70 MB of unneeded
debugging symbols. Remove those symbols with:</para>
<screen><userinput>strip --strip-debug /tools/lib/*
/usr/bin/strip --strip-unneeded /tools/{,s}bin/*</userinput></screen>
<para>These commands will skip a number of files, reporting that it does not
recognize their file format. Most of these are scripts instead of binaries.
Also use the system strip command to include the strip binary in /tools.</para>
<para>Take care <emphasis>not</emphasis> to use
<parameter>--strip-unneeded</parameter> on the libraries. The static
ones would be destroyed and the toolchain packages would need to be
built all over again.</para>
<para>To save more, remove the documentation:</para>
<screen><userinput>rm -rf /tools/{,share}/{info,man,doc}</userinput></screen>
<para>Remove unneeded files:</para>
<screen><userinput>find /tools/{lib,libexec} -name \*.la -delete</userinput></screen>
<para>At this point, you should have at least 3 GB of free space in
<envar>$LFS</envar> that can be used to build and install Glibc and Gcc in
the next phase. If you can build and install Glibc, you can build and install
the rest too.</para>
