5 | <para>It's time to enter our chroot'ed environment in order to install the
|
---|
6 | rest of the software we need.</para>
|

7 |
|
---|
8 | <para>Enter the following commands to enter the chroot'ed environment. From
|
---|
9 | this point on there's no need to use the $LFS variable anymore, because
|
---|
10 | everything a user does will be restricted to the LFS partition (since / is
|
---|
11 | actually /mnt/lfs but the shell doesn't know that).</para>

|

15 | <para>The -i option will clear all environment variables for as long as you
|
---|
16 | are in the chroot'ed environment and only the HOME and TERM variables
|
---|
17 | are set. The TERM=$TERM construction will set the TERM variable inside
|
---|
18 | chroot to the same value as outside chroot which is needed for programs
|
---|
19 | like vim and less to operate properly. If you need other variables
|
---|
20 | present, such as CFLAGS or CXXFLAGS, you need to set them again.</para>
|
---|
21 |
|
---|
22 | <para>The reason we do <userinput>cd $LFS</userinput> before running the
|
---|
23 | <userinput>chroot</userinput> command is that older sh-utils packages
|
---|
24 | have a chroot program which doesn't do the cd by itself, therefore
|
---|
25 | meaning that we have to perform it manually. While this isn't an issue
|
---|
26 | with most modern distributions, it does no harm anyways and ensures that
|
---|
27 | the command works for everyone.</para>
|
---|
28 |
|
---|
29 | <para>Now that we are inside a chroot'ed environment, we can continue to
|
---|
30 | install all the basic system software. You have to make sure all the
|
---|
31 | following commands in this and following chapters are run from within the
|
---|
32 | chroot'ed environment. If you ever leave this environment for any reason
|
---|
33 | (when rebooting for example) please remember to mount $LFS/proc
|
---|
34 | again and re-enter chroot before continuing with the
|
---|
35 | book.</para>
|
---|
36 |
|
---|
37 | <para>Note that the bash prompt will contain "I have no name!" This is
|
---|
38 | normal because Glibc hasn't been installed yet.</para>
