Summary

Provide a tool to help users migrate a Wubi installation to a dedicated partition

Implementation

• Rely on existing Ubuntu CD or USB stick. Create a Ubiquity branch registered with CIA

• When Ubiquity is started autodetect existing Wubi installations (OS-Prober -> find OS -> scan windows OS)

• If an installation is found ask the user whether they want to migrate or they want to do a fresh installation
• Show the partitioning page disabling options that are inappropriate (such as wiping the full disk or the partition hosting wubi)
• Confirmation Page
• mount partitions and clear if necessary (i.e. normal bottom half of partman)
  • Have to take care of /host /usr /home partitions and mount them accordingly (i.e. mount root.disk, then read fstab, then mount other disks.)
• copy - potential checksumming will depend on method of copying:
  • (see components/install which calls scripts/install.py)
  • dd + resize filesystem (only if we have a sane method of dding a sparse file)

    • partimage (backup suite that can skip zeros) http://www.partimage.org/Partimage-manual_Introduction

  • file-level copy as usual in ubiquity
• skip all extra setps except grub installation
• regenerate fstab from scratch
• remove lupin-support package
• install grub package and do usual grub installation
• regenerate initramfs
• (post-install) Notify the user that they can remove Wubi from the Windows side.
