Code review comment for lp://staging/~jpds/launchpad/fix_361650

Hello Jonathan,

Thanks for this patch -- I can see how this would be useful.

I don't have any serious issues with the database patch -- the uniqueness constraint looks correct to me. My main concern is that using the word 'official' to describe this new concept will create confusion with the already existing concept of 'official mirror'. Would 'primary_mirror' make sense?

Other than that, the db patch looks good to me.
