Public bug reported:
When there's a failure, this is what shows up in the lxc-start DEBUG-
leve log output:
lxc-start 1323586208.776 DEBUG lxc_console - using '/dev/tty' as
console

This generally happens when a lot of other containers are being brought
up and taken down, so it's entirely possible that it's some kind of race
condition, as in
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/720095. I don't yet
have a reproducible / reduced error case, unfortunately.
