easy LFS chroot script

In chapter 6.4 in the stable release of LFS you need to chroot into your build environment, and I have to keep rebuilding the chroot, and i keep going back to my PDF and retyping all the commands so i created on that would rebuild the environment by just calling my new script, then make it one better CP it into /usr/bin and make it executable
mount -v --bind /dev $LFS/dev
mount -vt devpts devpts $LFS/dev/pts
mount -vt tmpfs shm $LFS/dev/shm
mount -vt proc proc $LFS/proc
mount -vt sysfs sysfs $LFS/sys
chroot "$LFS" /tools/bin/env -i
HOME=/root TERM="$TERM" PS1='u:w$ '
/tools/bin/bash --login +h

just copy and past the above code into a new file and called it lfsroot then if you just want to make it into a command copy it into /usr/bin and you are ready to go, the script will mount the file systems and the enter the chroot environment
This has saved me plenty of time by not typing or copying and pasting commands, My next script will be a script that will tar and cd into the directory of source packages……look for it soon
