Hardy installation fails to see previous Gutsy or import user home folders
Gutsy was installed on sda1.
Booted Hardy 8.04 CD, chose Install.
Walked through steps until partitioner started up and asked where to install.
It offered to resize sda1 (7.10) and create a new partition after it (8.10).
Expected behavior: new version recognizes previous installation and offers to replace system while preserving /home directory.
Also, during account creation, it failed to recognize the user accounts on sda1. 'No user accounts were found to import'
