Pavel, Should we include this in the patchset ? Sukadev --- From: Sukadev Bhattiprolu <sukadev@xxxxxxxxxx> Subject: [PATCH] Allow signalling container-init Only the global-init process must be special - any other container-init process must be killable to prevent run-away processes in the system. TODO: Ideally we should allow killing the container-init only from ancestor containers and prevent it being killed from that or descendant containers. But that is a more complex change and will be addressed by a follow-on patch. For now allow the container-init to be terminated by any process with sufficient privileges.
