Verified on 4.5.0-0.nightly-2020-06-17-001505

Reproduction notes:
Apparently you can't create netns from an oc debug container because it doesn't have the "mountPropagation: HostToContainer" setting, so it is tricky to create the netns from the host.  Workaround was to ssh into the host from an ssh bastion and create the netns as the real root user.

If the netns is not created without rslave the stat -f type will be "tmpfs".

Also typo  `ip netns new` -> `ip netns add` 


success output:
