For some unknown reason "owner" makes it impossible to open bind mounted netns references as apparmor denies it. In the kernel denied log entry we see ouid=0 but it is not clear why that is as the actual file is owned by the real (rootless) user id. In abstractions/pasta there is already `@{run}/user/@{uid}/**` without owner set for the same reason as this path contains the netns path by default when running under Podman.
