# Need a config file that contains the drives to watch and how long they must
# be idle for before spinning down
#
# Need to determine if sg_start is installed, and if so, where
#
# Need to monitor field 13 of /proc/diskstats for each drive. Value unchanged
# from last time means idle, value changed means not-idle and presumed spun-up
#
# Need to maintain a flag for when we've spun the drive down, so we don't keep
# spinning it down every time we think it's idle
