-Detailed explanations:

+2) **init binary doesn't exist on rootfs**: Make sure you have the correct root FS type

    E.g. some serial consoles are unreliable due to serial IRQ issues (e.g.
    missing interrupt-based configuration).

    you should make sure that the script specifies an interpreter in its shebang
