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...
