Clone ES4 machine

[Marcelino Mata]

I have used rsync on live system to copy O/S between disk on the same
system and the copied disk worked fine.  Only did this once to prove it
can be done.  Probably not recommended but it can work.

I, too, am looking for a way to clone.  What I want to do is have 2
disks in a computer and make changes to the first disk.  If the changes
break things, I can swap the disks, re-clone the one I just made the
master to the now broken disk, and make adjustments to the changes I
just made.

I do this on SOlaris with ufsdump and ufsrestore script that can dupe a
disk in 10 minutes.

I don't want to reinvent the wheel, so I am looking for someone who has
already done this with system commands and a script.

Unfortunately, I work in a place where I cannot import software from the
Internet and install it.  I have only inherent OS functions to use.
