Share home directory between 2 18.04 installations

[Jack McGee]

So I have a broken 18.04 (#1) installation, and installed another 18.04 
(#2)instance beside it.

The new 18.04 (#2)cannot see the original home directory.


from the first installation:

mythuser at amethi:~$ cat /etc/fstab
# /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/sda2 during installation

I have verified the user mythuser on both installations has the same UID 
1000.

the home directory is empty on new installation.
