Shell from inside Emacs

Hi,

at Linux, did

sudo usermod -aG MY_NEW_GROUP "$USER"
newgrp MY_NEW_GROUP

Works fine from a new xterm.

But shell inside Emacs seems to read the environment only from start.
MY_NEW_GROUP is shown by ‘groups’ command only after restart of Emacs.

Is there a way to avoid the need for a restart?

Thanks,

Andreas
