at a later point, we'd like to have, optionally, also persistency files
on a seperate directory on the server for every node, so that all
clients are sharing a common chroot but are able to have files on their
own, but not through an unionfs layer (which consumes memory).

fedora does have this already within their config-netboot thing (but it
is implemented through an additional unionfs layer on the client side).

aufs[0] is in the new queue. as soon as it is accepted, i'll change
things in live-helper to be able to switch between unionfs and aufs at
build time. aufs is as far as i have seen so far, a drop in replecement
from the debian-live point of view.

[0] i've sponsored the uploads, they are also available here:
