usb mount script for sun rays

as you all know the sun ray ultrathin-clients support several types of devices connected to them, including serial and parallel devices, usb mass storage, pdas and so on. for a full list see the sun ray admin guide, chapter four. now when a usb mass storage device gets plugged in, the sun ray services mount it to /tmp/SUNWut/mnt/[username]/disk[integer]/. the user then needs to traverse the file system to get into the named directory which is applicable but quite a strange behavior for people who got used to windows (plug in usb-stick and it gets mounted as a lokal partition, then the user gets notified of it). because of this i have thought of a possibility to decrease user concerns and increase their positive experiences. yesterday i did a quick hack to check for mounted usb devices, link them to the users home directory and open a file browser to display the linked directory.

the script has a pitfall yet, because it supports only one usb device per user. so if the user connects two or more usb mass storage devices (should happen rarely) the scripts fails. i plan to code an option the select the desired device. perhaps some of my fellow readers want to supply this so i don't have to code it? :)

btw. using this script you have to unmount devices after usage of course. i will come up with the according script later.
