Public bug reported:
I'm using lxd with zfs block storage on xenial, and having issues with
trusty containers. I've witnessed this problem when trying to bootstrap
as well as after rebooting the host and a container failed to start.
In the latter case, the container that failed to start was the juju
controller:

I manually started it, but found that no upstart services were started.
Remembering this thread,
https://lists.ubuntu.com/archives/juju/2016-February/006698.html, I
checked /var/log/mountall.log in the machine-0 container, and sure
enough:
root@juju-5f4bd172-ad22-4726-8d84-47185ab31b54-machine-0:~# cat
/var/log/upstart/mountall.log
mount: permission denied
mountall: mount /sys/kernel/debug [187] terminated with status 32
mountall: Filesystem could not be mounted: /sys/kernel/debug
The problem persists if I stop and start the container. If I remount
/sys/kernel/debug on the host, then stop and start the container,
upstart succeeds and the juju controller starts up.
