My user has UID 1000 and primary GID 1000. It also belongs to GID 1001. Now I want to run a user level quadlet with GID 1001 as primary group. How can I do that?
What I’m trying to do: I have a nftables rule that filter traffic by GID. I need all traffic from a container / service get filtered. I’m using system level nftables.service so user level systemd slice will not work.
