ELN-extras will be a new build target and compose similar in behavior to ELN, but closer to EPEL in function. It will be a place to prepare and maintain packages that may be desired for EPEL N+1 while RHEL N+1 is still being incubated in ELN.

Current status

Detailed Description

This will essentially be an extension of Fedora ELN, with the primary difference being that the content in ELN-Extras will be defined by the Fedora/EPEL community, while ELN's content is largely decided upon by Red Hat management. This will offer users the opportunity to make sure their applications will work on upcoming releases of RHEL as well as providing a bootstrapping mechanism for EPEL. It will be far easier and quicker to get a compose of EPEL N+1 out the door if the initial packages have already been built for ELN-Extras.


Benefit to Fedora

This Change will enable application developers to keep up with impending changes in RHEL even before CentOS Stream becomes available for that release. Additionally, it provides a bootstrapping mechanism for EPEL, which will mean a much shorter gap between the launch of a new RHEL major release and the availability of the EPEL repositories.


  • Proposal owners:

High-level tasks

1. Create the tags and targets in Koji (see the release engineering ticket below). 2. Add support to Content Resolver for addon repositories [DONE] 3. Update the DistroBuildSync configuration to support building for ELN-Extras. 4. Configure ODCS to produce an ELN-Extras variant compose.

  • Other developers:

Aside from the release engineering tasks, anyone who wants to have a package appear in ELN-Extras will need to add it to the content set. This is not mandatory for any packager and we can ship the ELN-Extras repository empty if we so choose.

  • Policies and guidelines: N/A (not needed for this Change)

Documentation on how to add packages to the ELN-Extras content set and how to consume its compose will be written as part of this Change.

  • Trademark approval: N/A (not needed for this Change)
  • Alignment with Objectives:

Not specifically aligned with the currently-active Objectives. Loosely related to the previous Minimization Objective.

Upgrade/compatibility impact

N/A, this will be an entirely new compose and thus has nothing from which to upgrade.

How To Test

No specific testing is required for this Change, though any general OS and software management testing would be most welcome.

User Experience

Fedora will make available a new add-on repository for ELN, maintained by the Fedora Community.


This should be self-contained from a dependency perspective. The groundwork was already laid by ELN.

Contingency Plan

  • Contingency mechanism: We will not ship/advertise the existence of the ELN-Extras repository.
  • Contingency deadline: Final freeze
  • Blocks release? No


Documentation will be written as part of this Change.
