[Bug 1411294] Re: kernel panic during MAAS fastpath install of Vivid images

[dann frazier]

** Description changed:

- There appears to be an issue with the use of overlayfs in the image. See
- the attached screenshot for details. Immediately after that overlayfs
- error the kernel panics.
+ [Impact]
+ overlayfs support doesn't work with kernels > 3.18 which will, for example, break MAAS commissioning/deploying using trusty+hwe-v (when it exists).
+ 
+ [Test Case]
+ Create custom trusty image using the vivid kernel and attempt to commission a node with MAAS using that image.
+ 
+ [Regression Potential]
+ If the kernel detection code is buggy, it could regress functionality on older kernels (e.g. 3.13/3.16).
