Sorry, I didn't parse your message correctly.

Usually, you'd want to use the same VG for both installs. Otherwise, the
VG name will have to include a sequential number, and then be dependent
of installing with any other VG available.

Then we'd have: hostnameYYMMDDseqseq

The bigger it gets, the uglier it gets, but I don't see a solution
besides forcing the definition of the name by the user. That way, at
least the fault would reside completely with the user. ;)

VolGroup00/LogVol00 just isn't pretty, useful or conflict-free.
