# 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.
