End users sometimes want to install software that is not provided by Fedora. This policy lays out the extent to which Fedora Products can make it easier for end users to do that.
1) COPRs can provide RPMS with .repo files in them because Red Hat is the provider and assumes liability, but those cannot be included in the main Fedora repos per FESCo decree.
2) COPR repos may be searched for applications to install as long as the user is explicitly asked to enable the copr before installing packages from them.
3) General 3rd party repositories cannot be searched or enabled due to liability concerns.
(NOTE: "searched" in 2 and 3 was intended to cover searching by software. Clearly users can manually search for anything.)
4) FESCo is okay with pointing to specific free software repositories in the same way as COPR repos if they are approved by FESCo and Fedora Legal. They are not limited in the criteria that they can choose to apply.
5) For non-free sofware repositories, FESCo is not changing exisiting policy. Non-free software repositories are not allowed. Permission to make these discoverable via searching software would require a change in policy from the Fedora Board.
