Summary

This page is for discussion related to Wubi development in the Intrepid cycle.

Release Note

Further improve the user experience when using Wubi.

Possible New Features

  • d-i support (i.e. same hooks as lupin-casper)
  • Add bittorrent support to built-in download manager
  • Built-in cdburner (need to evaluate CD burning libraries)
  • Bootable USB device with ISO with casper-rw
  • HD-media like installation from HD (Target empty partitions?).
  • Grub2 (as recommended by bean123)
  • Better build scripts (nsis is available in the repositories)
  • Support for "large" distros such as ubuntu studio or edubuntu (support separate add-on CD directly? or leave it as pos-installation task? shall we automate such tasks somehow?)
  • support DVD
  • Use resizable image files (LVM or simply 4GB zeroed + nGB sparse, or qcow2 type of images or images that are contiguous for the first 4GB and sparse for nGB)
  • Support for "native" installations (installation inside a folder, no loopfile)
  • "My Documents" bookmark pointing to the appropriate windows folder (migration-assistant?)
  • Add "Use existing ISO" button, to use a pre-downloaded ISO (at the moment ISO and wubi.exe can be placed in the same folder, but it is not too obvious).

UI Changes

  • Can we further simplify the interface?
  • Changes to the accessibility page
  • Do we want to have advanced options?
  • Possiblility of a frontend rewrite in python or c++ and such

Porting Wubi to other platforms

  • Could use a native installation approach (installation inside a folder, no loopfile)
  • lubi (wubi for linux)
  • mubi (wubi for mac)

Porting Wubi To Debian

  • Requires D-I hooks.

  • Requires porting upstream all the changes to initramfs-tools, grub & co, sysvinit scripts, caspre/d-i initrd hooks, lupin-support.

  • Investigate the opportuinty of a tighter integration with the win32-loader project (at the moment it does netinstallation only).

Migration Tools (loopinstallation -> real partition)

  • To be discussed in separate session:
  • Support for loopinstallations within ubiquity (it should detect existing loopinstallations and offer to migrate them)
  • Simplified migration GUI.

Migration Page Mockup

Action:
 * Migrate the existing Wubi installation to a real Partition
 * Install Ubuntu
 
Install into:
 * Free space in hard disk #1 (sda, 8GB) 
 * Free space in hard disk #2 (sdb, 6GB)
 * Empty partition #2 of hard disk #1 (sda2, 26GB)
 * Empty partition #5 of hard disk #1 (sdab, 12GB)
 * Advanced Mode

Free up space for the new installation:
 [Resize an existing partition] [Delete an existing disk/partition]

The install-into list only contains safe items, I.E. items that do not contain any file and are large enough. For instance, if disk #1 is in use, and the user wants to dedicate the full disk #1 to the installation, he will have to click on "Delete an existing disk/partition", delete disk #1 and then select "Free space in hard disk #1" which will appear in the install-into list.

This is safer and clearer than merging the two operations into a single action such as "Install into disk #1", as in current ubiquity dialog. In particular, with the above suggestion, it is not possible to accidentally overwrite/delete any file unless the user explicitly selects "Delete an existing disk/partition" or (s)he uses the "Advanced Mode".

If there is no available free space or empty partition the Install-into list will instead display a message such as "No free space is available. You will need to free up some space first in order to continue the installation. A minimum of 4GB are required."

Resize partition dialog: 

 Squeeze [partition #1] in [disk #1]
 to 5GB [ =====|========= ] and  free up 10GB
 -----------------------------------------------------
 Partition Info: /dev/sda1
 Total size: 15GB
 In use: 4GB
 Label: mytarget
 Filesystem: NTFS
 Files: WINDOWS, temp, Program Files, RECYCLER
 -----------------------------------------------------
 [Resize Partition] [Cancel]

Delete partition dialog: 

 Delete: [partition #1 | all partitions] in [disk #1] 
 -----------------------------------------------------
 Partition Info: /dev/sda1
 Total size: 15GB
 In use: 4GB
 Label: mytarget
 Filesystem: NTFS
 Files: WINDOWS, temp, Program Files, RECYCLER
 -----------------------------------------------------
 [Delete Partition] [Cancel]

Advanced Mode (same as ubiquity):

  • Overwrite an existing disk/partition #skip disk/partitions where wubi is installed
  • Create multiple mountpoints
