That's when you launch a *container* and want it to be able to use
nested resource control.

We're talking about actual container users here. It's not turning on
resource control for all "privileged services", which is what we were
worried about here. Can you at least admit that when you yourself link
to the refuting evidence?

And if you've been "burnt quite heavily" by this, where is your bug
report to stop other users from getting "burnt quite heavily" as well?

All I read here is vague inflammatory language to spread FUD.

You might think sending these emails is helpful, but it really
isn't. Not only is it not contributing code, insights, or solutions,
you're now actively sabotaging someone else's effort to build something.
