Now you need a life media to continue.

From the live media mount the install containing /.

  # mkdir /mnt/install
  # mount /dev/sda1 /mnt/install/

Then rename /mnt/install/home and add a mount point for the new home.

  # mv -i /mnt/install/home /mnt/install/home.old
  # mkdir /mnt/install/home

Duplicate the current fstab.

  # cp -ip /mnt/install/etc/fstab /mnt/install/etc/fstab.old

Edit /mnt/install/etc/fstab

FROM

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>
# / was on /dev/sda1 during installation

IOW just change the last line.

That's it, now boot the install and start a user session.

Open a terminal and run

  $ echo "test" > old_home_vs_new_home_test.txt
  $ diff /home/$USER /home.old/$USER | grep Only\ in

So apart from this new file, there should be no diff.

  $ ls -hAl /home/$USER
  $ ls -hAl /home.old/$USER

Both /home look ok?

  $ mount | grep /home

mount shows /home?

If so, you could delete the old /home.

  $ sudo rm -Ir /home.old/

Again, it's better if somebody verifies that I didn't made a mistake by
accident, before you follow my advices.

Ralf
