When I installed 1.8, I was smart enough to create a separate /home partition. I don't want any of the existing configuration files to interfere with the default settings in 2.0, though.
What I THINK I want to do is:
- Boot from 2.0 Live DVD
- rename the /home folder of the primary user (e.g. from /home/theman to /home/theman-temp)
- install UUE2.0 with the primary user name as "theman"
- boot UUE2.0 from hard drive
- move documents, etc. (except configuration files) from /home/theman-temp to /home/theman
- delete /home/theman-temp
