Correct, just starting the container and shutting it down triggers the
issue, lxc-start will never exit and you'll need to kill it.

My test container didn't have anything special, it was a standard Ubuntu
container running on a standard Ubuntu system.

As I said, I also had a similar problem with a container having a
pre-start hook which caused it not to start at all and that started
working after the revert. Though I'm not entirely sure that this one
wasn't caused by the hook returning non-zero.
