# A script for use after hotswapping a D-bay drive
# when the device wasn't inserted originally.
# It will create a mount point, symbolic link to hdc
# and update fstab. Not very well tested yet :)
# Please note the hotswap program expects the device
# to refer to /dev/hdc rather than /dev/cdrom -- read the docs.
