# Short-Description: mdadmd daemon monitoring MD devices
# Description:       Start mdadmd to allow monitoring MD devices aka
#	Linux Software Raid. This is only meaningful for raid1, raid5
#	or  multipath arrays as only these have interesting state.
#	raid0 or linear never have missing, spare, or failed drives, 
#	so there is nothing to monitor.
