Quoting Andrew Pollock (debian-lists-2004@andrew.net.au):
Bit of a mouthful of a subject.
I'm wondering if it would be beneficial to automatically add the non-root
user created by base-config to a few groups, e.g. cdrom, floppy, audio,
video?
s/by base-config/by shadow
Let's assume the case of someone using d-i to install Sarge on a machine
that will be that person's desktop (hey that's me!). Most likely it will
only have the one user. The installation will be more useful "out of the
box" for that non-priviledged user if that user can access the cdrom, and
the floppy drive and make noises come out of the speakers.
See bug reports for the shadow package.....This feature has been asked
several times but its implications are non-trivial.
Suggestions have been made for adding this in base-config if, for some
valid reasons, this is not implemented in shadow.
