The /etc/systemd/network/ folder didn't exist by default, which caused static IP assignment via the kernel command line being broken (The format ip=<ip>::<gateway>:<netmask>:<hostname>:<iface>:none[:<dns1>[:<dns2>]] is documented in https://docs.flatcar-linux.org/ignition/network-configuration/#using-static-ip-addresses-with-ignition and parsed in the initramfs). Create the folder before trying to write a networkd unit into it. Reported in flatcar/Flatcar#148
