I'm CC'ing the Ubuntu Installer mailing list on this for the benefit
of anyone that comes across the same problem in the future.

It is not necessary to completely wipe the target partition. Select
manual partitioning and make sure the format box is not checked for
the root filesystem. This *will* delete any directories that ubiquity
will replace (/usr, /etc, /var, and the like), but it will leave your
home directory intact and carry over the UID and GID from the username
you've inputted, if the user already existed on the system. For the
curious, the code for this can be found here:
Hope that helps,
