WubiMigration

Summary

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

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.
