okay: to preface this note I must apologize beforehand for the fact I get easily confused. there is a reason for that which is that I had a traumatic brain injury in 1985. I typed in 'exit' until I got to the command prompt: lfs@debian:~$ the I su to root. Then I made the backups by cp -rf sources/ tools/ lfs.backups/ Now I: chroot "$LFS" /tools/bin/env -i HOME=/root and then I was going to "rm -rf" each individual directory but to make sure things were right: root@debian:/# ls bin etc lfs.backups lost+found opt run sources temptools usr boot home lib media proc sbin srv tmp var dev initrd.img lib64 mnt root selinux sys tools vmlinuz root@debian:/# exit exit lfs@debian:/$ su Password: root@debian:/# ls bin etc lfs.backups lost+found opt run sources temptools usr boot home lib media proc sbin srv tmp var dev initrd.img lib64 mnt root selinux sys tools vmlinuz The two directories are the same? To make sure they weren't I ls /home: root@debian:/# ls home/ lfs mike root@debian:/# chroot "$LFS" /tools/bin/env -i HOME=/root HOME=/root root@debian:/# ls home/ lfs mike So both directories are the same So what to do now?
