42<para>If your LFS partition is rather small, you will be glad to learn that you
43can throw away some unnecessary things. The executables and libraries you have
44built so far contain about 130 MB of unneeded debugging symbols. Remove those
45symbols like this:</para>
46
47<para><screen><userinput>strip --strip-unneeded /stage1/{,s}bin/*
48strip --strip-debug /stage1/lib/*</userinput></screen></para>
49
50<para>The first of the above commands will skip some twenty files, reporting
51that it doesn't recognize their file format. Most of them are scripts instead
52of binaries.</para>
53
54<para>Take care <emphasis>not</emphasis> to use
55<userinput>--strip-unneeded</userinput> on the libraries -- they would be
56destroyed and you would have to build Glibc all over again.</para>
57
58<para>To save another couple of megabytes, you can throw away the documentation
59and some of the bigger unneeded programs:</para>
60
61<para><screen><userinput>rm -r /stage1/share/{doc,info,man}
62rm /stage1/bin/{addr2line,gprof,nm,size,strings,strip}</userinput></screen></para>
63
64<para>You will now need to have at least 700 MB of free space on your LFS
65filesystem to be able to build and install Glibc in the next phase.</para>
