Hi,
I am totally not sure whether this is appropriate. I agree that this
behavior is a quick of many operating systems, but I don't think that
adduser should begin to document operating system quirks. People might
see this as an issue in adduser, which it isn't.
Greetings
Marc

Hello dear adduser maintainer(s),
I swear, *every* time I do `adduser user group` I have
to look up on the internet how to make that group available
to that user in a running shell session...
The attached patch adds two phrases to the "Add an existing user
to an existing group" paragraph that tells the reader to use
`newgrp` to achieve that and mentions `newgrp` in the
"SEE ALSO" section.
I'd be glad if you could include this in the man page so I
(and probably others) can stop looking it up on the internet
each time...
Best greetings and thank you for your work on `adduser`.
