Sorry.  I'm not going there.  You are entitled to do silly things if you want, 
but I don't have to help you.  Security exists for a reason - because people 
have a tendency to do things they shouldn't.

Yeah, it works.  But if you accidentally delete one of those delimiters while 
deleting passwords, you could end up unable to access your system.  It's much 
safer to stick with the tools provided for modifying those files (e.g., 
adduser, useradd, usermod, kuser, etc).

You're absolutely correct, but I maintain that it would be stupidity on my 
part to help you do something like this.  On your own head be it.  In the 
same time, _I've_ never had a problem with security either, but I take 
precautions to try to keep it that way.

Again, you've lost me.  If you won't use "sudo" and you won't suid root, your 
only option is to log into the root account - sudo would be simpler.

Yes - /etc/apt/sources.list.  Though, I'd agree with the other poster who 
pointed out that there's no guarantee of a smooth upgrade from Kubuntu to 
Sarge.
