For what it's worth, I wrote that message, and (try to) always test
things like that to make sure they work. It seems I missed that,
though.
The way those options are explained in pw(8) is misleading. Apparently
"additional" was used in the sense of "all groups that are not the
primary group", not in the sensing of adding groups.
Here is the current version (rewrapped):
-G grouplist Set additional group memberships for an account.
grouplist is a comma, space or tab-separated list of
group names or group numbers. The user's name is
added to the group lists in /etc/group, and removed
from any groups not specified in grouplist. Note: a
user should not be added to their primary group with
grouplist. Also, group membership changes do not
take effect for current user login sessions,
requiring the user to reconnect to be affected by the
changes.
Here is how I propose to rewrite that:
-G grouplist Set secondary group memberships for an account.
grouplist is a comma, space, or tab-separated list of
group names or group numbers. /etc/group is modified
to include the user's name in the groups specified in
grouplist. The user's name is removed from all
groups not specified. Group membership changes do not
take effect for current user login sessions,
requiring the user to reconnect to be affected by the
changes. Note: do not add a user to their primary
group with grouplist.
Feedback welcome.
