- <title>Cleaning Up</title>
- <para>Finally, clean up some extra files left around from running tests:</para>
- <screen><userinput>rm -rf /tmp/*</userinput></screen>
- <para>From now on, when reentering the chroot environment after
- exiting, use the following modified chroot command:</para>
- <screen role="nodump"><userinput>chroot "$LFS" /usr/bin/env -i \
- HOME=/root TERM="$TERM" \
- PS1='(lfs chroot) \u:\w\$ ' \
- PATH=/bin:/usr/bin:/sbin:/usr/sbin \
- /bin/bash --login</userinput></screen>
- <para>The reason for this is that the programs in <filename
- class="directory">/tools</filename> are no longer needed. Since they are no
- longer needed you can delete the <filename class="directory">/tools</filename>
- directory if so desired.</para>
- <note>
- <para>Removing <filename class="directory">/tools</filename> 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 <ulink url="&blfs-root;"/>).</para>
- </note>
- <para>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 <xref
- linkend="ch-system-bindmount"/> and <xref
- linkend="ch-system-kernfsmount"/>.</para>
- <para>There were several static libraries that were not suppressed earlier
- in the chapter in order to satisfy the regression tests in several packages. These
- libraries are from binutils, bzip2, e2fsprogs, flex, libtool, and zlib. If desired,
- remove them now:</para>
- <screen><userinput>rm -f /usr/lib/lib{bfd,opcodes}.a
- rm -f /usr/lib/libbz2.a
- rm -f /usr/lib/lib{com_err,e2p,ext2fs,ss}.a
- rm -f /usr/lib/libltdl.a
- rm -f /usr/lib/libfl.a
- rm -f /usr/lib/libfl_pic.a
- rm -f /usr/lib/libz.a</userinput></screen>
- <para>There are also several files installed in the /usr/lib directory with a
- file name extention of .la. These are "libtool archive" files and generally
- unneeded on a linux system. None of these are necessary at this point. To
- remove them, run:</para>
- <screen><userinput>find /usr/lib -name \*.la -delete</userinput></screen>
- <para>For more information about libtool archive files, see the <ulink
- url="&blfs-book;/introduction/la-files.html">BLFS section "About Libtool
- Archive (.la) files"</ulink>.</para>
