10 | <para>From now on, when you exit the chroot environment and wish to reenter
|
---|
11 | it, you should use the following modified chroot command:</para>
|
---|
12 |
|
---|
13 | <screen><userinput>chroot "$LFS" /usr/bin/env -i \
|
---|
14 | HOME=/root TERM="$TERM" PS1='\u:\w\$ ' \
|
---|
15 | PATH=/bin:/usr/bin:/sbin:/usr/sbin \
|
---|
16 | /bin/bash --login</userinput></screen>
|
---|
17 |
|
---|
18 | <para>The reason for this is that, since the programs in <filename
|
---|
19 | class="directory">/tools</filename> are no longer needed, you may want to
|
---|
20 | delete the whole directory and regain the space. Before actually deleting the
|
---|
21 | directory, exit from chroot and reenter it with the above command. Also, before
|
---|
22 | removing <filename class="directory">/tools</filename>, you may want to tar it
|
---|
23 | up and store it in a safe place, in case you want to build another LFS system
|
---|
24 | soon.</para>
|
---|
25 |
|
---|
26 | <note><para>Removing <filename class="directory">/tools</filename> will also
|
---|
27 | remove the temporary copies of Tcl, Expect and DejaGNU, which were used for
|
---|
28 | running the toolchain tests. If you want to use these programs later on, you
|
---|
29 | will need to recompile and re-install them. The installation instructions are
|
---|
30 | the same as in <xref linkend="chapter-temporary-tools"/>, apart from changing
|
---|
31 | the prefix from <filename class="directory">/tools</filename> to <filename class="directory">/usr</filename>. The
|
---|
32 | BLFS book discusses a slightly different approach to installing Tcl, see
|
---|
33 | <ulink url="&blfs-root;"/>.</para></note>
|
---|
34 |
|
---|
35 | <para>You may also want to move the packages and patches stored in <filename
|
---|
36 | class="directory">/sources</filename> to a more usual location, such as
|
---|
37 | <filename class="directory">/usr/src/packages</filename>, and remove the
|
---|
38 | directory -- or simply delete the whole directory if you've burned its contents
|
---|
39 | on a CD).</para>
