In podman 1.0 if you executed a command like: podman run --user dwalsh --cap-add net_bind_service alpine nc -l 80 It would work, and the user dwalsh would get the capability, in podman 2.0, only root and the binding set gets the capability. This change restores us back to the way podman 1.0 worked. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>
