# Script to scan and mount etherdrive blades. If a directory exists, the blade should be mounted.
# Newly detected blades will be mounted on $mountdir/XY if the device is /dev/etherd/eX.Y
# Removes mount points for blades that have gone down
# Mounts individual blades (no RAID) and checks for partition. Script will attempt to mount first partition.
