Once #755 is done (and ideally also #756), we'll need a way to serve repositories from the Debusine web application. From our [planning document](https://docs.google.com/document/d/12CvqlRa_vBjjaQItizwsHww-6HXx9-QPU2cpqxnfjvs): MUST: Views to access indexes and packages in an apt-compatible layout - Including possibility to access historical versions of those when they are available - Including views for debian:archive combining multiple debian:suite in a single mirror - Include public keys used to validate the repository in some standard location (perhaps extend Signed-By to include full key material, or provide instructions to clients?) - by-hash - Serve repositories from a separate domain (avoid XSS attacks etc., and it’ll make more sense to apt)
