There was no conscious choice to use LVM here. I do not have the

partitioning scheme I wanted to use was not presented as an option by 
the installer in an earlier build. In a previous install there had been 
a way of compressing the existing system so that it occupied 50% of the 
total drive space. The installer then would write a new partition using 
the other 50% of drive space freed up. With my current knowledge of LVM, 
that's as good an answer as I can give.

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.
