Please review the following Fedora 45 System Wide Change Proposal: https://fedoraproject.org/wiki/Changes/DisableVendorChangeByDefault

Summary of the change:
Starting with Fedora Linux 45, DNF5 will no longer automatically replace an installed package with a version from a different vendor during upgrades, downgrades, or dependency resolution. Users who want to intentionally switch a package to a different vendor will need to do so explicitly, for example using the --from-vendor= option.

Release Engineering involvement:
The implementation is limited to two configuration file changes in the fedora-release-common package. I assume this change does not require a mass rebuild or any changes to installer image generation or update package delivery.

Targeted release: Fedora Linux 45

Okay, I went through the proposal. Once the approval goes through for the change, do you want releng to handle the file configuration changes? Or, is it something you are looking for reviews?

This ticket is mainly a heads-up about the upcoming System-Wide Change for F45 and a request for your review of the proposal.

I will prepare and file the PR with the necessary configuration file changes myself. I assume this change shouldn't be an issue for releng. The theoretical risk during the transition could occur if there is a step in the release engineering pipeline or build chain where a package is installed and subsequently replaced (via upgrade/reinstall/downgrade) by a package from a different vendor. Without explicitly allowing the vendor change, this could now fail or block.

points
01
 A task that is simple, small, and has very little uncertainty. It should be easy enough for any team member to pick up and complete quickly, without a lot of discussion or research.

  
points
02
 This is a task that is slightly more complex or larger than a "1." It might involve two or three simple steps, but the outcome is still very clear and there's little uncertainty.

  
points
03
 Medium-sized task with some noticeable complexity. It might require a bit more thought or collaboration. The steps are well-defined, but it's not a trivial change.

  
points
05
 A significant piece of work. It has more complexity and a higher degree of uncertainty than smaller tasks. It might require some research, a design discussion, or collaboration across multiple teams.

  
points
08
 Complex task with a lot of uncertainty. It's often the largest size that a team will consider for a single sprint. It likely requires a detailed breakdown and multiple team members to complete.

  
points
13
 Any task that feels like it's a "13" or more is considered an Epic. These are too large and uncertain to be worked on in a single sprint and should be broken down.

  
Priority
High
 This is for work that is critical and needs to be addressed in the next sprint. It's often for urgent bugs, important features, or a major piece of technical debt that is blocking other work.

  
Priority
Low
 This is for work that is good to do but not urgent. It's a candidate for being worked on when there's extra time or when it rises in importance. It can stay in the backlog for a longer period.

  
Priority
Medium
 This is for important work that should be done soon, but isn't as urgent as a high-priority item. It will likely be considered for the next 1-2 sprints.

  
Sprint Status
Blocked
 Work items that cannot progress due to external dependencies, blockers, or issues that need resolution.

  
Sprint Status
Done
 Work items that have been completed, reviewed, and integrated. No further work is needed within the current sprint.

  
Sprint Status
In Progress
 Work items currently being worked on by a team member. Active development, research, or implementation is happening.

  
Sprint Status
Review
 Work items that are complete but need review, testing, or approval before being marked as done.

  
Sprint Status
To Do
 Work items that are committed to the sprint but haven't been started yet. These items are ready to be picked up by team members.

  
Technical Debt
Work that addresses shortcuts, workarounds, or suboptimal implementations that were done previously to meet deadlines. These items improve code quality, maintainability, or performance without adding new features.

  
Work Item
Bug
 Issues where the system is not working as intended or designed. Bugs represent deviations from expected behavior.

  
Work Item
Epic
 Large initiatives that are broken down into multiple smaller work items (user stories, tasks, bugs). Epics represent significant features or projects that span multiple sprints.

  
Work Item
Spike
 Time-boxed research, investigation, or proof-of-concept work to reduce uncertainty or explore solutions. Spikes help inform future development decisions.

  
Work Item
Task
 Used to break down larger user stories into smaller, manageable implementation pieces. They focus on the specific technical steps needed to deliver the user story's value.

  
Work Item
User Story
 User-facing features or functionality that can be framed from a user perspective, describing what someone wants to accomplish and why.
