6.72. Cleaning Up
Finally, clean up some extra files left around from running tests:
rm -rf /tmp/*
From now on, when reentering the chroot environment after exiting, use the following modified chroot command:
chroot "$LFS" /usr/bin/env -i \
HOME=/root TERM="$TERM" PS1='\u:\w\$ ' \
PATH=/bin:/usr/bin:/sbin:/usr/sbin \
/bin/bash --login
The reason for this is that the programs in /tools are no longer needed. Since they are no
longer needed you can delete the /tools
directory if so desired.

Note
Removing /tools 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 http://www.linuxfromscratch.org/blfs/).
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 Section 6.2.2, “Mounting and Populating /dev” and Section 6.2.3, “Mounting Virtual Kernel File Systems”.
Finally, 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:
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
