Note that CentOS 6 will not. RedHat rewrote anaconda to use the
hostname in the volume groups, which is very helpful to avoid just
this situation.

Nico,

Thanks for the response.  Does this mean there is nothing I can do to
make this happen.  Is there a way to change the name of "VolGroup00"?
If so I have not found it yet.  I see that I can change "LogVol00", but
have not figured out how to chanage "VolGroup00".

Maybe, I am finally beginning to understand logical volumes. :)
