<pre>I have two users (user1 and user2), but for a special purpose I want to
maintain a single store of files in the user1 home directory.
So I added user1 and user2 to the "users" group, and reassigned the Group
property for /home/user1 from "user1" to "users."
I think that change automatically propagated to all the user1
sub-directories, but I can't remember for sure. It's possible that I
manually changed the sub-directory permissions, perhaps even before the
change to /home/user1.
In any case, I thought that permission setup would automatically propagate
to any new sub-folders, but I just created user1/Documents/Documentation,
and it has Group: "user1."
Can I configure this for the behavior I'm looking for?

<pre>user1 belongs to two groups, user1, and users. The first group, is his
primary group.
Change the primary group number of users user1, and user2, in
/etc/passwd (this file contains the user number, and primary group
number).

</div><font size="-1">This opens up yet more questions. /etc/passwd only
contains the original GID's for user1 and user2. It does not
reflect that both have now been also added to the "users" group.
So it seems that more than one user/group configuration system is
being supported.<br>
<br>
I have been reading today the manpages for adduser, addgroup, and
adduser.conf. Interestingly, it does not document where it stores
the configuration information -- perhaps because adduser and
addgroup are only front-ends for useradd and groupadd. There is
no mention of /etc/passwd, for instance.<br>
<br>
But apart from that, Lubuntu's GUI tool for Users and Groups is
users-admin (which I used for my customizations), and I have not
yet found any handy documentation for that. There may be
something somewhere at <a href="http://library.gnome.org" target="_blank">library.gnome.org</a>, but I have not found it
yet. But poking around a bit in the interface, I see that it does
not even show that user1 is a member of the user1 group, and
likewise with user2. So again, that indicates to me that more
than one user/group configuration system in effect.</font><br>
