Managing module defaults in Fedora
Setting or changing a default stream or a default installation profile of a module constitutes a major behavior change as defined in the Fedora Updates Policy. The following rules apply:
Module stream defaults MUST be only changed in an upcoming Fedora release
Changes of stream defaults should be communicated by a Fedora Change based on the change’s significance and its maintainer’s best judgement. When in doubt, file a Change.
Changes of the default stream of a module are not permitted within a released Fedora without the approval of FESCo.
Introducing a new default stream not replacing any existing default stream or a traditional package is not considered a change. That means it can be done.
Submit an issue to Fedora Release Engineering in pagure.io/releng. Consider submiting a Fedora Change. Please specify which releases of Fedora should have which streams/profiles by default in the initial ticket.
To check the current defaults, have a look at the fedora module defaults repository.
Please note that if the module stream masks part of the Traditional RPM repos (e.g it replaces an existing RPM or it introduces a non-trivial set of conflicts) it may not be made a default stream without the express permission of FESCo. Release Engineering will be responsible for escalating any PR that is questionable on this point to FESCo for a final decision.
