Restarting LXC containers after a panic, power-fail or everything else is not the concern of basic LXC, it related to
your host init script or your HA stuff (guest could have been restarted somewhere else) or things like Ganeti, Openstack...

For me it's a concern of security, LXC provide isolation through namespaces bewteen host and guests, this kind of stuff
would break this isolation.
For a guest not knowing on which host it is running is not about of obscurity but information security.
(obscurity is, IMHO, not about giving information but hiding technical details and how things works, but yes security
through obscurity is not a solution)
