Finally going to bite the bullet and update my main machine, one question though. How will I have to handle existing user directories and information on the /home partition if I do a fresh install of FC4? What will happen when during the first run I have to create a user and this user's directories etc already exists? I am going to back up all the information to DVD anyway as well as leaving copies on other partitions. Also, will my raid0 drive (data drive) cause / be a problem?
