I have read through and I can see why you are failing.
With autodev you are failing with mknod /dev/null.
Without autodev you are creating pts (I assume to represent /dev/ttyN)
before creating the user namespace and then there is a permission
problem with chmod.
Both of which seem like correct behavior from the kernels standpoint.

Let me suggest setting lxc.tty = 0. So you don't get tty creation
and see how far that goes.
