Interesting idea that I had not thought of.
However, my primary goal is to be able to have a backup of the
disk/partition that it runs from.  This will save me from hardware failure.

So, if I dd the partitions then I think I need to run lilo on the disk
to make it boot the correct partition.  This is where I am unsure of the
details.  I am still reading lilo man page...
