This was actually covered in this thread (first post, actually) by
Torfinn Ingolfsen:

"Better to use this:
   pw groupmod dialer -m myuser
it will ony affect the dialer group, and not mess with any other groups.
"

The above will add the user "myuser" to the "dialer" group while
leaving the user's other group intact as well.

I've been following this thread, have this question:

How does one add a user to additional groups without removing the user from 
groups the user is already in?

I just looked at the new manpage from a fresh svn update of src tree.

Ah yes! You are correct! For some reason I was mixing my "pw usermod"
and Linux "usermod" (where you use the -aG to append). My fault
entirely. Continue with your correct request for the update of the

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.

While your solution is not incorrect, your assumption on the
proposed/given solution from the port is. The '-G' switch appends the
given group to your users already given groups. So, if a user belongs
to groups admin,wheel,test and you run the suggested "pw" command from
the port, your user will now be in groups admin,wheel,test,dialer.
It's the '-g' (lower-case) switch you want to avoid...

That being said, your suggestion does the exact same thing. So,
really, either works.

devel/arduino - bad advice given in pkg-message

2016-03-25 Thread Torfinn Ingolfsen 
Hello,
The pkg-message for the devel/arduino port contains this:

"To allow serial port locking, add your user to the dialer group:"
"pw usermod myuser -G dialer"

It is  good to explain what a user have to do to get serial access.
However, if you use that pw command, it will remove your user from any
other groups than the dialer group. Which might be annoying.
Better to use this:
   pw groupmod dialer -m myuser
it will ony affect the dialer group, and not mess with any other groups.
HTH
