I'll change it soon. >=20 Thanks for your answer. I sort of figured gconcat would be the way to go. And yes, it would be useful to allow creation with only one provider (sorry for the provider/consumer confusion earlier), especially with a number of repos of this kind. Still, what are the chances of data corruption when adding more providers and then growfs? Growfs comes bundled with warnings at least... -- Markus =D6rebrand, Systems administrator @ Operax
