Comment 23 for bug 1263738

I figured out what's happening. lxc sets up /dev/kmsg as a symlink to /dev/console, init fopens kmsg, and suddenly it owns the console. Not sure whether the fix is to handle kmsg differently or special-case it in upstart to be opened with O_NOCTTY. I'll leave it to Serge and James to figure that out, and in the meantime I'll attend to the kernel patch.
