|
|---|
| [da9119c] | 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
|

| [b822811] | 11 | <para>Enter the following commands to enter the chroot'ed environment. From
|
|---|
| [6370fa6] | 12 | this point on there's no need to use the $LFS variable anymore, because
|
|---|
| [81a47c0] | 13 | everything a user does will be restricted to the LFS partition (since / is
|

| [b822811] | 18 | <para>The -i option will clear all environment variables for as long as you
|
|---|
| [5e2cb65] | 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
|

| [b822811] | 23 | present, such as CFLAGS or CXXFLAGS, you need to set them again.</para>

|---|
| [81a47c0] | 27 | following commands in this and following chapters are run from within the
|
|---|
| [607c7370] | 28 | chroot'ed environment. If you ever leave this environment for any reason
|
|---|
| [24bb7622] | 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
