@fnordahl Hi! Let's keep the discussion about bug 1701297 in that bug since it is focused on the change in behavior between the Xenial release kernel and the HWE kernel. That's not what this bug is about. John is investigating the change in behavior issue. Jamie's previous investigations of overlay

@Frode, Users running 2.2 *already* have the apparmor=0 work around for *ephemeral* environments only. For users running previous versions, we recommend you upgrade immediately, provided that 2.0 and 2.1 are out of support. If you decide not to upgrade, your options are: 1. Use a HWE kernel (suc

This problem has surfaced again with recent MAAS Ubuntu images. One report in bug 1701297. I have information about at least two other end users hit by the problem. Adding a workaround by setting apparmor=0 kernel parameter in MAAS 2.2 will not help users that are running previous versions. @jdst

Closing the MAAS task as it the referenced bug is marked Fix Release.
