booting with init=/bin/bash and running the files /etc/rcS.d/S* manually
it seems to be fsck.* and mount who has dependacies on /usr.
To fix this, theese packages needs to un-/usr-merged:
libmount1
libblkid1
libpcre2-8-0
libuuid1
uuid-dev
busybox can replace the mount command, but there is no fsck.* in
busybox.
