Script that can be used during Mac OS X startup to mount a disk image to any path on the filesystem.

attach-disk-image.sh

#!/bin/sh
##
# Mount my development websites folder
#
# NOTE: Because this uses Mac OS X mounting techniques, all mac format
#       images are supported and many other UNIX filesystem formats.
#       (My Development Sites image is stored encrypted.)

# Location of the image to be mounted
IMAGE="$HOME/Documents/Development Sites.sparsebundle"

# Path to an empty folder where the contents of the image can be found
MOUNT="$HOME/Sites"

# Do the magic
# -owners on = Honor file/folder permissions in image
# -nobrowse = Don't show in Finder (-mountpoint is still visible)
# -mountpoint = Attach to a folder.
hdiutil attach -owners on -nobrowse -mountpoint "$MOUNT" "$IMAGE"
