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, since the programs in /tools are no longer
needed, the directory can be deleted to regain space. Before actually
deleting the directory, exit from chroot and reenter it with the above
command. Also, before removing /tools, tar it up and store it in a safe
place in case another LFS system will be built.

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 or tar it up and keep it to build another final system.

Removing /tools will also remove the temporary copies of Tcl, Expect,
and DejaGNU which were used for running the toolchain tests. To use
these programs later on, they will need to be recompiled and
re-installed. The installation instructions are the same as in Chapter
5, apart from changing the prefix from /tools to /usr. The BLFS book
discusses a slightly different approach to installing Tcl (see
http://www.linuxfromscratch.org/blfs/).

Removing /tools will also remove the temporary copies of Tcl, Expect,

The packages and patches stored in /sources can also be moved to a
more usual location, such as /usr/src/packages. The entire directory can
also be deleted if its contents have been burned to a CD.

I suggest:
If you wish, the packages and patches stored in /sources can be moved to
a more usual location, such as /usr/src/packages or in some other
location that suits your needs. Either way, after you reboot and create
your non-root user account, you should make the sources directory
(wherever you choose to put it) writable by this non-root user.
-----------------------------------------------------------------------
This brought up a philosophical debate in my mind. If the book mentions
moving the sources, but then proceeds to move them to a directory where
only root can write, ISTM that this can be mis-interpreted as "you have
to download sources as root to be able to save them". If someone has to
be root to save new sources in the suggested directory then how far is
that from being root to build?
Apart from this line of thinking, another thought was why does the book
suggest this at all? Is this something that should be left as an
exercise to the reader instead of something that a new reader will
blindly follow (and they most likely will blindly follow)? That is why I
added "if so desired", "If you wish", and "wherever you choose".
