Bug Description
[Impact]
overlayfs support doesn't work with kernels > 3.18 which will, for example, break MAAS commissioning/
[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).

From the image we can see that the maas installer is using overlayroot to allow customisation of the image. It is not handling the new workdir= parameter which prevents successful mounting of root, and aborts the boot.
