AppArmor has difficulties mediating filesystem access when overlayfs is involved. That's a known issue but isn't one that is easily solved due to the internal design of overlayfs and its use of private vfsmounts. It also isn't something that we're planning to fix for the 17.10 cycle.

I thought that we recently investigated a similar issue to this and determined that MAAS wouldn't enable AppArmor when it is initially provisioning a machine. I can't remember the exact details and I'm not confident that was the final solution but maybe that rings some bells for the others that were involved.
