Solaris Network Administration Scripts

Here's a little script I was working on back in the college lab last month. I was facing a very trivial solaris administration problem. I've installed SXDE 1/08 on 120 systems in one of our biggest computer labs long back (more on how I did that later). Now I needed a way to do certain tasks on each of those systems like changing the boot order, changing the solaris GRUB splash image, setting the hostname for each system based on its current IP address...,more.
