That is my point - adduser will print a warning if the user already
exists.

So you need to check to make sure the user doesn't exist first, before
attempting to add it. Or you get a stupid warning appearing when
upgrading packages.

Not according to the man page[1]:

       --quiet
              Suppress progress messages.

or in a practical sense either:

[EMAIL PROTECTED]:~# adduser aaa
adduser: The user `aaa' already exists.
[EMAIL PROTECTED]:~# adduser --quiet aaa
adduser: The user `aaa' already exists.

(this is sarge/stable - maybe it has changed in unstable?)

Good.

Note:
[1] What is a "progress" message?
