LANDesk stores its data files in the /Library/Application Support/LANDesk/data directory. However, there is a uuid file for LANDesk that, if you put the LANDesk client in your image will need to be deleted. The uuid is in the /Library/Preferences/com.landesk.uuid.plist property list. If you rm this file as a postflight imaging task then your client can be deployed on your image:
rm /Library/Preferences/com.landesk.uuid.plist
