Config:

    In the current version, you just need to edit the configuration
    section of sleepdisk itself to set it up for your computer.
    List the drives you want to sleep, with their idle times in
    minutes.  (You can also specify how often you want to check,
    which determines the granularity of the idle times.  Not too
    important unless you want very short idle times.)

To enable auto-start on boot:

    Edit sleepdisk.service and replace the YOUR... paths with yours.

    > cd /etc/systemd/system
    # cp [...]/sleepdisk.service .
    # systemctl daemon-reload
    # systemctl enable sleepdisk

To start immediately, after the above:

    # systemctl start sleepdisk
