Gregory's Server@pid_eins the point is that sometimes you need that context. If I'm in a toolbox sudo has to allow me to get things done in the context of the toolbox and not of the system root. I. principle I agree with you about suid, I just don't see how you can get rid of it with containers.
@swick @pid_eins For this use case, you can re-enter the toolbox/container but directly as root instead of your user. It needs some plumbing but it's doable.
