Summary

The CF community should add support for Ubuntu Resolute Raccoon (26.04 LTS) as the next CF Linux operating system. This RFC proposes producing a Resolute-based BOSH stemcell, validating it across the CF component ecosystem, and providing a clear migration path for release authors and operators—particularly for the removal of the runit package, which is likely the most impactful change the stemcell itself introduces.

If the intention is to have Resolute GA before the EOL of Jammy, we should mention that the community will need to support three stemcell lines in parallel until Jammy's EOL, and cf-deployment will need to have validation for all three of them.

Supporting three stemcells is basically possible, but will of course increase cost as we need yet another validation environment.

Is there a process we need to go through to approve the cost increase? I'd like to be testing all three.

RFC looks good from my perspective (ARD WG). As soon as the new stemcell is available, we can set up an additional environment to deploy CF on Raccoon and run CATs. We would provide an ops file to opt-in for the new stemcell. The migration to Noble and cflinuxfs5 is still ongoing, so it's too early to communicate a clear timeline for the Raccoon adoption.

I've pushed some minor updates to address concerns.

I'd like to propose that we move into the Final Comment Period for accepting this RFC.
