Kubuntu Xenial current missing casper module in initrd

[DougL]

Latest images of Kubuntu does not have the casper module in the initrd.img system so persistent storage does not work. It appears to have been this way for a few months.

drops to busybox with persistent listed in boot options and using debug= shows the casper module can't be found.

Image obtained from:
zsync http://cdimage.ubuntu.com/kubuntu/xenial/daily-live/current/xenial-desktop-amd64.iso.zsync

I've now tested Ubuntu 16.04.2 also and it results in the same:
 /cow format specified as overlay and no support found

I'm using Customizer-gui to rebuild the iso after adding "overlay" to /usr/share/initramfs-tools/modules.

That fixed it in Kubuntu 16.04.02 so it's probable it's the solution in default Ubuntu 16.04.02.

This worked in the December 30 2016 current live snapshot and I know its been broken for the past couple of months.
