Thanks.  Good advice.  What we really need is someone to maintain a
central registry for UUID generation for EFI and GPT based ID's.   Since
drives are getting bigger and bigger, GPT is probably going to be the
standard 5 years from now, so sooner is better than later.  I will
regenerate a new UUID using these tools and update the software.

Thanks for the help.
