We had earlier discussed a solution for this (sometime last year) by making
volgen remember xlator names and not reassign them. Copying KP with who I
had discussed this to quite a level of detail. Have you guys spoken about
this? IIRC the solution KP and I discussed was more generic and could also
support retaining user made changes/customizations to the volfiles.
