[Bug 1040996] Re: Not offered "Install alongside" if other OS isn't Windows or Ubuntu

[Dmitrijs Ledkovs]

Dear original submitter - can you please reconfirm the disk partitioning
scheme used? Was it LVM with separate /boot?

One thing to note is that from the logs the reporter's machine suggests that it is installed on top of LVM.
Currently LVM is ambiguous from auto-resize point of view.

>From implementation point of view, the resize (aka alogside install) is available when:
* existing installation is single full disk (e.g. full disk linux/windows)
* where there is sufficient amount of free space available in that partition to perform a resize
* there is sufficient amount of space left to install ubuntu if resize is attempted 
* the partitioner understands how to resize that file system

This is pre-requisites =)
Now the caveats

* the resizing may fail if the extends are allocated in a such a way
that a resize without defragmentation is not possible, or not supported
enough by existing tools.

This is ambiguous from LVM point of view, because:
* do you want to resize the VG & create a separate normal partition - OR - do you want to create ubuntu lvm volumes within that group?
* where should the boot loader go to?

Sorry for not checking the auto-collected logs more carefully when first
looking into the bug. Thank you mpt for updating the Partitioning
Options Matrix ;-) I was previously interpolating options while reading
it.

Title:
  Not offered "Install alongside" if other OS isn't Windows or Ubuntu

Status in “ubiquity” package in Ubuntu:
  Triaged

Bug description:
  System is a MacBook Intel Core Duo - 2.4 Ghz - 4 Gig of RAM - 250 Gig Hard Drive.
  Was attempting to perform Test Case uri-001 - on Lubuntu 12.10 build of Aug 21 2012
  Previously installed System was Fedora 14
  According to the Test Case procedure under the heading, "Allocate drive space", the installer is supposed to offer a choice of installing Lubuntu alongside the previous system. 

  Instead it offered me the following choices:

  Replace Fedora 14 with Lubuntu
  Something else

  It should be noted that this was my second attempt at performing this
  procedure. During the first attempt (see comment under bug #1034954),
  the aim was to partition available hard drive space between the
  previously installed system - Lubuntu 12.10 build of August 14 2012
  and the system being installed from Live Desktop Disk - Lubuntu 12.10
  build of August 21 2012. A crash occurred  at the same point as
  referred to in that bug report. I added my comment.

  As suggested by Mr. Ledkovs (comment 9 under bug report #1034954),
  after booting the live install CD, I opened a terminal and ran
  Ubiquity from there.

  Thinking that perhaps the two systems were too much alike to be
  installed together, I decided to replace the previous system with
  something else (Fedora 14).

  That seems to have led to somewhat inconsistent behaviour from
  Ubiquity at this point in the Test Case.
