[Bug 1504781] Re: lxc-test-ubuntu hangs forever in trusty-proposed with Linux 3.13.0-66: AppArmor denies /dev/ptmx mounting

[Stephen Gaito]

Hello,

As of this morning's security roll out of the Linux 3.13.0-66 kernel,
this bug *is* effecting *live* LXC containers ;-(

(I am using Trusty 14.04 LTS - I note that recently built Trusty 14.04.3
machines are not rolling out Linux 3.13.0-66 as they have Linux
3.19.0-30-generic)

Reading between the lines of @jjohansen's comments (#8, #10), I updated
my /etc/apparmor.d/abstractions/lxc/start-container apparmor
configuration file from the existing:

>   mount options=bind /dev/pts/ptmx/ -> /dev/ptmx/,

to

>   mount options=(rw, bind) /dev/pts/ptmx/ -> /dev/ptmx/,

Unfortunately I can confirm that this *does* *not* solve the problem.
Have I misunderstood something?

I can also confirm that I have exactly the same error messages listed
above in @pitti's comment #4.

Is there any know work-around/fix?
