This is not specifically correct. The road to compromising the container is
Even if container is privileged and the container owner has root access inside
the container, gaining any host advantage would be hard if not impossible,
unless the host configuration is far from sane.

LXD by default is "secure" in sense that even if container is compromised, the
effective UID the container user is running from has no rights on the host.

Unnecessary in real-world application.
