My question is what exactly is necessary to back up when I want to do a clean install? I did a clean install of Tiger and I had problems with errors when i tried restoring my user folder. Particularly, with the Library folder. I am wondering if, when I copy a folder over, does it delete the contents of the original folder? I am thinking that my Mail quirks are a result of missing files. When I do a clean install, should I be able to just copy of my user folder and apps folder and be all set? Should I do this logged in to my normal account?
