[lxc-devel] Shutting down containers properly

Yes, obviously that also works, but then you need to manually update
the inittab of a container and rewire reboot/power failure actions to
cause a shutdown as you describe.

I'd really prefer shutting down a container just worked out of the box
without any strange modifications to /etc/inittab for sysvinit. I
really think shutting down containers properly is a functionality that
LXC should support out of the box.
