Also remember that you should change your root password to "root," if you want to give out copies without compromising your own password.
I have a separate partition with root and guest, that I use to remaster after all the latest updates. I have all the programs I use in this partition, but none of the data. I have separate partitions with "MyMusic", "MyDocuments". "MyPictures" which I can access from anywhere Linux. If, you are still using Windows much, those partitions probably should be formatted NTFS, so Winders can see them.
So If I bork my main OS, I can reinstall and still have full access to all my data files.
