I'm unclear why the default user is part of the dialout group on server
images either. If you look at the history of user-setup, you'll see
that we once (10 years ago) had the default user in dialout, but this
was reverted because it wasn't needed for ppp access (that uses dip) and
users shouldn't have direct access to serial ttys by default. In
particular, if there is a serial console, having access to the tty means
the user may have access to intercept root passwords being sent on the
line.
Do you know where the dialout group is being added by default on
servers, and if there has already been discussion of this issue?
I expect that the GPIO devices are not serial TTYs. Is there a good
reason to use the dialout group for these devices instead of a different
(perhaps new) group?
