I asked about this behaviour not too long ago, and John said it
was intentional, as a kind of safety catch. Accidentally setting
up a shared repository can lead to your data not being stored
where you thought it was, which could be disastorous.

However, I don't know if that's a big enough concern to force
the inconsistency with "init" here.

Thanks,
