I'm getting ready to reinstall from my 9.04 CD.

Before doing so:

1. What files and directories do I need to backup?

/home
/boot/grub/menu.lst
/boot/grub/images
/boot/grub/splashimages
/opt

Anything else?


2. Is there anyway to search and replace my current owner name and group
name attached to files so that I can use a completely new name? As it
is, currently my owner name and group name are different because of
creating a new account and moving my /home directory there.

I'll be backing up to the second hard drive and reformatting the first
one. Most of my /home directory type files are there already,
documents, pictures, videos, etc. Should I maybe just start the home
directory from scratch so everything is reset?

3. B.t.w. - I've already dumped my package list, via dpkg -l so I can go
back and reinstall things. Is there a way to dump my added repositories
and keys?
