I am having to re-install Debian on my web server, but I give access to the server to many friends who have their sites hosted on the server. I don't know much about server administration, but I wondered if it is possible to save the users in some way-shape-or-form so that I don't have to re-add the users and have to give them all new passwords.
Also, any tips on recreating the os as it is now after the installation would be great!
Cheers, Jamie
