Entering the chroot'ed environment It's time to enter our chroot'ed environment in order to install the rest of the software we need. Enter the following command 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).
cd $LFS && chroot $LFS /usr/bin/env -i HOME=/root \    TERM=$TERM /bin/bash --login
The TERM=$TERM construction will set the $TERM value inside chroot to the same value as outside chroot which is needed for programs like vim and less to operate properly. Now that we are inside a chroot'ed environment, we can continue to install all the basic system software. A user has to make sure all the following commands in this and following chapters are run from within the chroot'ed environment. If he ever leaves this environment for a reason (say when rebooting or something) he has to remember to mount $LFS/proc again like he did earlier and to re-enter chroot before continuing with the book. Note that the bash prompt will contain "I have no name!". This is normal; Glibc hasn't been installed yet.
