Have you ever added users to a group and they do not have access to the rights of that group until they login again?
Instead of telling them to log out and login again (sounds like MS solution?) they can type:
newgrp name_of_a_group
For more details read
man newgrp
New version of portage adds support for licence acceptance for specific packages.
sun-jdk requires now acceptance of dlj licence (in /usr/portage/licenses)
If you do not want to get into more details simply add
ACCEPT_LICENSE=”dlj-1.1″
to your /etc/make.conf
You can also set this to
ACCEPT_LICENSE=”*”
but you won’t receive and error during installation of licensed software.
