  9. <title>Cleaning Up</title>
  10. <para>Finally, clean up some extra files left around from running tests:</para>
  11. <screen><userinput>rm -rf /tmp/*</userinput></screen>
  12. <para>From now on, when reentering the chroot environment after
  13. exiting, use the following modified chroot command:</para>
  14. <screen role="nodump"><userinput>chroot "$LFS" /usr/bin/env -i \
  15. HOME=/root TERM="$TERM" PS1='\u:\w\$ ' \
  16. PATH=/bin:/usr/bin:/sbin:/usr/sbin \
  17. /bin/bash --login</userinput></screen>
  18. <para>The reason for this is that the programs in <filename
  19. class="directory">/tools</filename> are no longer needed. Since they are no
  20. longer needed you can delete the <filename class="directory">/tools</filename>
  21. directory if so desired.</para>
  22. <note>
  23. <para>Removing <filename class="directory">/tools</filename> will also
  24. remove the temporary copies of Tcl, Expect, and DejaGNU which were used
  25. for running the toolchain tests. If you need these programs later on,
  26. they will need to be recompiled and re-installed. The BLFS book has
  27. instructions for this (see <ulink url="&blfs-root;"/>).</para>
  28. </note>
  29. <para>If the virtual kernel file systems have been unmounted, either manually
  30. or through a reboot, ensure that the virtual kernel file systems are mounted
  31. when reentering the chroot. This process was explained in <xref
  32. linkend="ch-system-bindmount"/> and <xref
  33. linkend="ch-system-kernfsmount"/>.</para>
  34. <para>Finally, there were several static libraries that were not suppressed earlier
  35. in the chapter in order to satisfy the regression tests in several packages. These
  36. libraries are from binutils, bzip2, e2fsprogs, flex, libtool, and zlib. If desired,
  37. remove them now:</para>
  38. <screen><userinput>rm -f /usr/lib/lib{bfd,opcodes}.a
  39. rm -f /usr/lib/libbz2.a
  40. rm -f /usr/lib/lib{com_err,e2p,ext2fs,ss}.a
  41. rm -f /usr/lib/libltdl.a
  42. rm -f /usr/lib/libfl.a
  43. rm -f /usr/lib/libfl_pic.a
  44. rm -f /usr/lib/libz.a</userinput></screen>
