We shouldn't treat OS recovery partitions the same way as other ntfs
partitions, and indeed recovery partitions have different labels and
partiotion type IDs to declare them as such. (especially when users
don't have any other installation media).

Title:
  'Erase Ubuntu [version] and reinstall' with 12.04 beta2 does not
  respect existing partitioning scheme

Status in “ubiquity” package in Ubuntu:
  Confirmed

Bug description:
  When installing 12.04 beta2 from the Live CD and choosing 'Erase
  Ubuntu [version] and reinstall', the installer simply wipes the root
  partition, creates a new swap partition and installs everything on the
  root partition, instead of respecting the existing partitioning
  scheme.

  My existing 11.10 installation had the following partitioning scheme:
  - /boot /dev/sda5
  - root on /dev/sda8
  - /home on /dev/sda6
  - swap on /dev/sda7
  While walking through the 12.04 beta2 installation steps, the installer properly detected the 11.10 install and provided several options to proceed.
  In the past I always selected 'Something else' because I always distrusted the other 'automagic' options.
  For this release I figured I should try out if my distrust was still valid, and chose 'Erase Ubuntu 11.10 and reinstall'.

  After the installation, I noticed that instead of re-using the existing partitioning scheme, the installer did the following:
  - split up /dev/sda8 into a root and swap partition
  - root on /dev/sda9 (new)
  - swap on /dev/sda8 (new)
  - /dev/sda5 (existing /boot) not mounted
  - /dev/sda6 (existing /home) not mounted
  - /dev/sda7 (existing swap) untouched

  IMHO, it should have respected the original partitioning scheme and
  re-use this, or at the very least prompt me on what it would (or even
  better - ask me what it should) do with the existing partitions. As a
  user, I expect this behavior since the description of the 'Erase
  Ubuntu 11.10 and reinstall' option cleary states that it 'will delete
  all documents, photos, music and any other files.'
