I need to write a script to where the lower half does not execute until the current shell runs an exit or logout command. How can I do this? The script I need this on is below.
mount -v --bind /dev $LFS/dev &&
mount -vt devpts devpts $LFS/dev/pts &&
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\$ ' \
PATH=/bin:/usr/bin:/sbin:/usr/sbin:/tools/bin \
/tools/bin/bash --login +h
#logout
#umount -v $LFS/dev/pts
#umount -v $LFS/dev/shm
#umount -v $LFS/dev
#umount -v $LFS/proc
#umount -v $LFS/sys
