initrd shall mount overlayfs as root-dir

Creating an overlayfs is easy

mkdir /mnt/nfs
mount -v -t nfs -o vers=4 172.16.56.90:/srv/nfs /mnt/nfs/ # readonly nfs-export

mount -t tmpfs -o size=100M none /mnt/tmpfs/
mkdir /mnt/tmpfs/upper
mkdir /mnt/tmpfs/work

mkdir /mnt/overlayfs
mount -t overlay overlay -o lowerdir=/mnt/nfs,upperdir=/mnt/tmpfs/upper,workdir=/mnt/tmpfs/work /mnt/overlayfs

Is there any hook out there like liveroot, discussed here https://bbs.archlinux.org/viewtopic.php?id=193461.

Liveroot is using an HD (or USB-stick) as ro-media. My is a ro-NFS.

How can I get initrd to mount root as an overlayfs like above?
