In the past with arch installs, new users have always been added to the 'users' group. Now that is not being done.
In short, this is OK; your user doesn't need to be mentioned in /etc/groups after his primary group. If he is mentioned, then the primary group is also his supplementary one (which is anyway automatic).
A while back, the default primary group for all new users was "users". It's not anymore: an individual group is created for each new user. One can disable USERGROUPS_ENAB in login.defs to get the old behavior.
This is done to save space in /etc/group on systems with large number of users.
So each user gets a home directory, generates log info under /var/log upon login/logout, /etc/passwd and /etc/shadow grow linearly in the number of users, but we are going to shave a few bytes off /etc/group? That's hard to believe. -- Gaetan
