Hola @haircommander 👋, v1.29 Enhancements team here.

I am just checking in as we approach enhancements freeze on 18:00 PDT on Thursday 6th October 2023..

This enhancement is targeting stage beta for v1.29 (correct me, if otherwise)

Here's where this enhancement currently stands:

• KEP readme using the latest template has been merged into the k/enhancements repo.
• KEP status is marked as implementable for latest-milestone: { v1.29}. KEPs targeting stable will need to be marked as implemented after code PRs are merged and the feature gates are removed.
• KEP readme has up-to-date graduation criteria
• KEP has a production readiness review that has been completed and merged into k/enhancements. (For more information on the PRR process, check here).

For this KEP, we would just need to update the following:

• For this PR to be approved: Add restrospetive KEP for ProcMount and target at Beta #4266

The status of this enhancement is marked as Tracked for Enhancements Freeze. Please keep the issue description up-to-date with appropriate stages as well. Thank you!

Sorry for the confusion @haircommander, this is actually currently At Risk for Enhancement Freeze until #4266 is approved. We'll update the status once the PR goes in. Let me know if you have any questions- Thanks!

Hello 👋, 1.29 Enhancements Lead here.
Unfortunately, this enhancement did not meet requirements for v1.29 enhancements freeze.
Feel free to file an exception to add this back to the release tracking process.

#4266 is awaiting PRR approval. Please file an exception and once the PRR review is complete this should fulfill all the enhancement freeze requirements.

Thanks!

@haircommander, what's the “One-line enhancement description” for this KEP?

[pacoxu]

@npolshakova https://groups.google.com/g/kubernetes-sig-release/c/emPOBgXxu0Q/m/JxEx-ZrcBgAJ?utm_medium=email&utm_source=footer

Your updated deadline to make any changes to your KEP is 18:00 PST Monday 9th October 2023.

The exception is approved by v1.29 release team. However, we may miss the deadline again 🤣.

[npolshakova]

@pacoxu It looks like this won't be making it into 1.29 from the slack discussion: https://kubernetes.slack.com/archives/C2C40FMNF/p1697033013866149?thread_ts=1696609849.513439&cid=C2C40FMNF

@tjons, this KEP has already undergone PRR reviews in the previous release. We were waiting for userns support, which wasn't available at that time. So from a PRR perspective, we are already covered.

OK, thanks! Updated to tracked for enhancement freeze 🚀
