Natty: Installer fails to resolve old partition with /home

Binary package hint: installation-report

Previous installations and partitioning on my notebook were:

/dev/sda1 - NTFS with Windows XP, about 43 GB
/dev/sda2 - extended partition with Ubuntu 10.04 LTS (32-bit)
/dev/sda5 - formatted to be swap area, about 2.2 GB
/dev/sda6 - system partition, about 20 GB, formatted to be ext4 mounted on /
/dev/sda7 - user partition, about 53 GB, formatted to be ext4 mounted on /home

Now, when installing Natty beta2 I decided to keep Windows XP intact and completely replace Lucid by Natty. There were several basic partitioning options offered during installation (1: completely erase old installations, 2: erase only previous ubuntu Lucid installation a put Natty instead, 3: some manual partitioning). The second option looked to be exactly what I wanted to do. The installer even promised me to erase all my user data in the previous ubuntu installation. Hence I opted this way.

After installation I found out that Natty was installed completely only to the small partition previously used for system (not for user data). Of course, since this partition was not too big, I quicky ran into problems with insufficient disk space on this partition.

The installer even ignored my old swap partition (sda5) and created a new one (sda8) by cutting off a portion of the old system partion. I.e. the installation resulted into two swap partitions and the installer did not make what it promissed to do (it promissed to erase all user data from my older ubuntu installations).

I propose that in any case (i.e. also when the option 2 is chosen) user should obtain a quick view of partition list with short description what is going to be done with particular partition. Of course, user should see this information BEFORE the formatting process starts.

Additional info:

* My system: Ubuntu 11.04 beta 2, i386 variant
* My machine: Fujitsu-Siemens AMILO Pro V3205 (a 32-bit notebook)
