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

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

<para><screen>&c6-chrootcmd;</screen></para>

<para>The -i option will clear all environment variables for as long as you
are in the chroot'ed environment and only the HOME, TERM, PS1 and PATH
variables are set. The TERM=$TERM construction will set the TERM variable
inside chroot to the same value as outside chroot which is needed for
programs like vim and less to operate properly. If you need other variables
present, such as CFLAGS or CXXFLAGS, you need to set them again.</para>

<para>Now that we are inside a chroot'ed environment, we can continue to
install all the basic system software. You have to make sure all the
following commands in this and following chapters are run from within the 
chroot'ed environment. If you ever leave this environment for any reason
(when rebooting for example) you must remember to enter chroot and mount 
$LFS/proc again (as will be discussed later) before continuing with the
book.</para>

<para>Note that the bash prompt will contain "I have no name!" This is
normal because Glibc hasn't been installed yet.</para>
