  --renice-priority <PRIORITY>
    Reset the nice priority value of the script and all its children
    to the desired PRIORITY. MUST be an integer (between "-19" and 19).
    Negative (higher) values MUST be enclosed in double quotes '"'.

  --reionice-priority <CLASS> <PRIORITY>
    Reset the ionice priority value of the script and all its children
    to the desired CLASS. MUST be an integer:

    PRIORITY MUST be an integer:
    between 0 (highest) and 7 (lowest) priority.

  - You MUST be 'root' to run this script.
