The user can use the command "mail" to add users to his group. :-)

The mail is sent to the person that can lay hands on the fileserver
to type "newuser group +new_member".  Even if there are members
of the adm group with write permission on /adm/users, unless someone
types at the fileserver "users", it won't take till a reboot.

Yet another example where Plan9 security works.

This stuff is not necessary to change a password at least.  That
info is managed from the auth server which has a network interface.

I've been thinking of how to allow network access to the file server
besides the "connect a serial cable to a cpu server and use consolefs".
Perhaps a file like /adm/cons which provides read/write access to the
console thread.  Then you put users in the adm group with read/write
group perms on /adm/cons to get to it.  Comments?
