Hello firejail developers,

I want to use bumblebee optirun in firejail with --overlay.
Without --overlay it works.
With --overlay user's groups other than users are gone, causing bumblebee unusable. Even sudo firejail --join to join it and usermod -aG bumblebee. In /etc/groups shows my user name, but user wasn't really added into that group.

Any solutions?
Thank in advance.

@garywill @rusty-snake Is this still an issue? If so we should mark it as a bug.
