  --allow-unrelated-histories

    By default, git merge command refuses to merge histories
    that do not share a common ancestor. This option can be
    used to override this safety when merging histories of
    two projects that started their lives independently. As
    that is a very rare occasion, no configuration variable
    to enable this by default exists and will not be added.

    getentropy() will succeed unless:

    [EFAULT]
    The buf parameter points to an invalid address.
    
    [EIO]
    Too many bytes requested, or some other fatal error occurred.
