Summary

A partitioning tool for Ubuntu Expess.

For automatic partitioning, we would like to share code with the existing installer component (partman). This will be best accomplished by providing it as an installable binary package (in addition to an installer component), so that it can be added to the live seed and used in a standard environment. partman uses debconf progress indicators, so some consideration is required in order to provide a consistent progress bar in the installation tool.

For advanced/interactive partitioning, we will extend an existing partitioning tool. The selection and development of this tool are discussed in GraphicalPartitioningTool. The installer must unmount all hard disk filesystems and deactivate swap before acting on the partition table, or launching an external partition editor.

Rationale

Scope

Design

Choosing a disk

Partitioning the disk

Another system on this disk

(Appears if one other system detected on the chosen disk)

It looks like the Seagate 18.2 GB hard disk has another system, "Windows 98",
on it already. What do you want to do with "Windows 98"?

(*) Leave it there, and choose another disk for Ubuntu
    To choose another disk, click "Go Back".

( ) Put Ubuntu alongside, so you choose a system on each startup
    If you choose this option, you'll need to decide how much space
    should be reserved for each system.

( ) Erase it, and replace it with Ubuntu
    Warning: This will delete all documents, programs, and other
    files on the disk.

( ) Specify partitions manually (advanced)

Other systems on this disk

(Appears if more than one other system detected on the chosen disk)

It looks like the Seagate 18.2 GB hard disk has three other systems
on it already: "Mac OS", "Mac OS X", and "DebianPPC". What do you
want to do with them?

(*) Leave them there, and choose another disk for Ubuntu
    To choose another disk, click "Go Back".

( ) Put Ubuntu alongside, so you choose a system on each startup
    If you choose this option, you'll need to decide how much space
    should be reserved for each system.

( ) Erase them all, and replace them with Ubuntu
    Warning: This will delete all documents, programs, and other
    files on the disk.

( ) Erase just these ones, and replace them with Ubuntu:
    +-----------------------------+-+
    |[ ] Mac OS                   |A|
    |[ ] Mac OS X                 |:|
    |[ ] DebianPPC                |V|
    +-----------------------------+-+

( ) Specify partitions manually (advanced)

Partition the disk

(Appears if dual-/multiple-booting)

Once Ubuntu is added to the disk "Seagate HD", there will be 4.8 GB left
for documents and other files you add later. How much of this space do
you want to allocate for each system?

      Ubuntu: [ 2.4]H GB =====V=====
  Windows 98: [ 2.4]H GB =====V=====
Leave unused: [   0]H GB V==========
       Total:   4.9   GB

(Perhaps the "Leave unused:" row is unnecessary?)

Advanced partitioning

gparted minus its toolbar.

Showing progress

The partitioning process should take only a small percentage (10 %?) of the total progress bar.

We can accurately estimate time remaining for resizing + partitioning, but we can't accurately estimate time remaining for resizing + partitioning + copying files.

Implementation

Code

Data preservation and migration
