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 system?"
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?
