From now on when you exit the chroot environment and wish to re-enter it, you should run the following modified chroot command: chroot $LFS /usr/bin/env -i \     HOME=/root TERM=$TERM PS1='\u:\w\$ ' \     PATH=/bin:/usr/bin:/sbin:/usr/sbin \     /bin/bash --login Additionally, now that all software has been installed, there is no longer a need for the /tools directory. You may delete it. As this will also remove the temporary copies of Tcl, Expect and DejaGnu, which were used for running the toolchain tests, you will need to recompile and re-install them on your LFS system if you want to use these programs later. Also you may now want to move the contents of /sources to /usr/src/packages or something similar (or simply delete them if you've burned them on a CD) and delete the directory.
