10 | <para>From now on, when reentering the chroot environment after
|
---|
11 | exiting, 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, the
|
---|
20 | directory can be deleted to regain space. Before actually deleting the
|
---|
21 | directory, exit from chroot and reenter it with the above command.
|
---|
22 | Also, before removing <filename class="directory">/tools</filename>,
|
---|
23 | tar it up and store it in a safe place in case another LFS system will
|
---|
24 | be built.</para>
|
---|
25 |
|
---|
26 | <note><para>Removing <filename class="directory">/tools</filename>
|
---|
27 | will also remove the temporary copies of Tcl, Expect, and DejaGNU
|
---|
28 | which were used for running the toolchain tests. To use these programs
|
---|
29 | later on, they will need to be recompiled and re-installed. The
|
---|
30 | installation instructions are the same as in <xref
|
---|
31 | linkend="chapter-temporary-tools"/>, apart from changing the prefix
|
---|
32 | from <filename class="directory">/tools</filename> to <filename
|
---|
33 | class="directory">/usr</filename>. The BLFS book discusses a slightly
|
---|
34 | different approach to installing Tcl (see <ulink
|
---|
35 | url="&blfs-root;"/>).</para></note>
|
---|
36 |
|
---|
37 | <para>The packages and patches stored in <filename
|
---|
38 | class="directory">/sources</filename> can also be moved to a more
|
---|
39 | usual location, such as <filename
|
---|
40 | class="directory">/usr/src/packages</filename>. The entire directory
|
---|
41 | can also be deleted if its contents have been burned to a CD.</para>
