    growisofs - what does rbu and ubu mean?

    I am just curious about the output of growisofs. What does RBU and UBU mean?

    The Acronyms are "Ring Buffer Utilisation" and "Unit Buffer Utilisation"

    The "Ring Buffer" is a memory buffer created and maintained by growisofs' builtin dd. It is 32 MB by default, according to the code I was just reading - if that is still the case, it might be time to increase that! - there has to be a config somewhere, but I am getting off track.
    The "Unit Buffer" is the buffer inside the DVD drive. By appearances, growisofs tries to keep it at around 60%
