[mirror-admin] where are all the indices of the repository?

[Carlos Carvalho]

I'd like to have a list of ALL indices of the repository used by the
package managers.

I'm thinking about not using --delay-updates any more, therefore I'd
have to pull packages first and indices later to avoid breaking the
mirror in the meantime. I suppose the indices are in */repodata but this
is too important to just guess, so I'd like to have an answer from
those who are well versed in the repository architecture.
