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?)
