Podman Machine crashes if run as root. When creating the machine, we write the ignition so that the UID of the core user matches the UID of the user on the host. We by default, create the root user on the machine with UID 0. If the user on the host is root, the core UID and the Root UID collide, causing a the VM not to boot.
