5 | <para>It's time to enter our chroot'ed environment in order to install the
|
---|
6 | rest of the software we need. Before you can chroot you need to change to
|
---|
7 | the <emphasis>root</emphasis> user since only user
|
---|
8 | <emphasis>root</emphasis> can use the <userinput>chroot</userinput>
|
---|
9 | command.</para>
|
---|
10 |
|
---|
11 | <para>Enter the following commands to enter the chroot'ed environment. From
|
---|
12 | this point on there's no need to use the $LFS variable anymore, because
|
---|
13 | everything a user does will be restricted to the LFS partition (since / is
|
---|
14 | actually /mnt/lfs, but the shell doesn't know that).</para>

17 |
|
---|
18 | <para>The -i option will clear all environment variables for as long as you
|
---|
19 | are in the chroot'ed environment and only the HOME, TERM, PS1 and PATH
|
---|
20 | variables are set. The TERM=$TERM construction will set the TERM variable
|
---|
21 | inside chroot to the same value as outside chroot which is needed for
|
---|
22 | programs like vim and less to operate properly. If you need other variables
|
---|
23 | present, such as CFLAGS or CXXFLAGS, you need to set them again.</para>
|
---|
24 |
|
---|
25 | <para>Now that we are inside a chroot'ed environment, we can continue to
|
---|
26 | install all the basic system software. You have to make sure all the
|
---|
27 | following commands in this and following chapters are run from within the
|
---|
28 | chroot'ed environment. If you ever leave this environment for any reason
|
---|
29 | (when rebooting for example) you must remember to enter chroot and mount
|
---|
30 | $LFS/proc again (as will be discussed later) before continuing with the
|
---|
31 | book.</para>
|
---|
32 |
|
---|
33 | <para>Note that the bash prompt will contain "I have no name!" This is
|
---|
34 | normal because Glibc hasn't been installed yet.</para>
