i found out that installing unionfs-fuse works as a solution for this problem 
(a retry with another flashdrive got the system to boot properly)

BUT fuse is not really a solution since overlayfs or aufs are faster..

the problem narrows down to one question

"why is overlayfs or aufs not available at boot time on the live

i tried with an additional kernel parameter UNIONFS=overlay  and immediately drop to a busybox again..

both modules can be loaded when the live system is running so the
problem probably resides in the initramdisk?

  using casper > 1.340 causes live system to drop to busybox (

Status in casper package in Ubuntu:

Bug description:
  Release:        16.04

  Package: casper
  Version: 1.376

  what should happen: the live system should boot properly
  what happens: the live system drops into busybox

  i created a systemimage of kubuntu 16.04 with "systemback" 
  the live system boots into busybox and displays the following message:

  "(initramfs) /cow format specified as aufs and no support found"

  i had this problem before on kubuntu 14.04.03

  it seems that downgrading to casper 1.340 resolves this problem (but
  downgrading on 16.04 is problematic / not possible)

  the current installed version of casper is 1.376
