I think what Gianmarco is wondering about is not why each user has a
seperate group, but why each user is listed explicitly in /etc/groups.
Since their primary group is already the group with their username, there
is no need to have their name in /etc/group. All that is needed is the
group entry with no user. ie., now it looks like:
marcs:*:1000:marcs
but it could look like:
marcs:*:1000:
and still do the same thing.
AFAIK, it just does that because it wants to. Helps make it a
little more explicit about what the groups are for I guess.
