FWIW, I'm getting the systemd issue w/o NFS, on a regular 9p virtfs.

| $ sudo mmdebstrap --architecture=riscv64 lunar rv-rootfs http://ports.ubuntu.com

and the rootfs qemu config:
 |  -fsdev local,id=root,path=/path/to/rv-rootfs/,security_model=none \
 |  -device virtio-9p-pci,fsdev=root,mount_tag=/dev/root \
 |  -append "root=/dev/root rw rootfstype=9p rootflags=version=9p2000.L,trans=virtio,cache=mmap,access=any security=none earlycon console=tty0 console=ttyS0"
