You're dreaming. You can't nest groups, they can only contain users. > Is there a good tool to simplify this "group reference" behavior? It's a > pain to add users to all group entries that they should have access to. `groupadd` `groupdel` `groupmod` Much better than editing /etc/group directly. > When changing the /etc/group file it takes a while for the change to take > effekt.

Once you've added yourself to a group, logout and back in again for the change to take effect. Alternatively, use `newgrp` to become a member of the new group _for_the_current_shell_only_. > A previous post to gentoo-user mentions pwconv and grpconv, but I haven't > seen any benifit to that, a relogin/reboot is still needed. `pwconv` and `grpconv` are nothing to do with this. They toggle between encrypted and plaintext group passwords. As you're not using group passwords, this doesn't apply. Hope that clarified a few points for you. -- Kind regards Greg Bolshaw Consultant Linux Technologies http://www.linuxtechnologies.co.uk/
