  <title>Cleaning Up</title>

  <para>Finally, clean up some extra files left over from running tests:</para>

<screen><userinput>rm -rf /tmp/*</userinput></screen>

  <para>There are also several files in the /usr/lib and /usr/libexec
  directories with a file name extension of .la. These are "libtool archive"
  files. On a modern Linux system the libtool .la files are
  only useful for libltdl.  No libraries in LFS are expected to be loaded
  by libltdl, and it's known that some .la files can break BLFS package
  builds.  Remove those files now:</para>

<screen><userinput>find /usr/lib /usr/libexec -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>

   <para>The compiler built in <xref linkend="chapter-temporary-tools"/> and
   <xref linkend="chapter-chroot-temporary-tools"/> is still partially
   installed and not needed anymore. Remove it with:</para>

<screen><userinput>find /usr -depth -name $(uname -m)-lfs-linux-gnu\* | xargs rm -rf</userinput></screen>

   <para>Finally, remove the temporary 'tester' user account created at the
   beginning of the previous chapter.</para>

<screen><userinput>userdel -r tester</userinput></screen>
