O.k.
I made a rudimentary initramfs (see attached), but I'm not sure if I did it
the right way. The problem is, that the rootfs remains mounted (to the
unreachable mount-pount /fscache) after switch_root.
How can one get some statistics from cachefilesd? It looks like the cache
isn't filled very much: I copied /usr (of the cached root-filesystem)
to /dev/null and the cache gets about 13M of data whereas /usr is more than
1G of data.
