[Bug 377613] Re: jaunty install: formatting root partition changes uuid

[Phillip Susi]

Reformatting means a new UUID.  Performing a new install includes
installing grub, and generating a new config that will reference the new
uuid.

Title:
  jaunty install: formatting root partition changes uuid

Status in “ubiquity” package in Ubuntu:
  Invalid

Bug description:
  Binary package hint: ubiquity

  Attempting to install Xubuntu Jaunty to replace an existing Kubuntu
  Intrepid.

  Because the install was a total failure (separate bug raised) I had to
  restore from my backups. However, having done so and attempted to
  reboot, Grub failed with "error 15 file not found".

  After spending a lot of time trying to reinstall Grub and not getting
  anywhere, I spotted that the UUID of my root partition had been
  changed by the install process, so not surprisingly, the UUID in
  menu.lst was incorrect. Editing this file allowed my computer to boot
  into the restored system.

  I would suggest that this shows that changing the UUID of filesystems
  during installation is an undesirable behaviour.
