I think the way you've invoked it there it will be trying to act as a
client to the (supposed to be) already running upstart.
"exec /sbin/init" might avoid that (I don't know how it decides to be
client vs. server) but I'd suggest that you boot without init=/bin/sh
and instead let Upstart get launched as the actual init.
