NOTE: This KEP was implemented in 1.4 and went beta in 1.11 and long predates PRR. I migrated the KEP to the new template and completed the PRR requirements as best I could. I think I put a note on the KEP for where the copy-pasting from the beta KEP ended.

The feature flag has defaulted to on for at least all current supported releases. We would like to graduate this in 1.21 and follow up on any remaining usability work in a separate KEP.

There may be some follow-ups required to improve usability, but I do not believe this should block graduation.

There was a note about unsafe sysctls and usability. Maybe we can add a graduation criteria to just document that on the website with workarounds so we can graduate this rather than worry about more code fixes in this release. @pacoxu

any scheduling enhancement we make around a node that is configured to allow unsafe sysctls would be a distinct feature.

just one change requested, which is the best kind, because it removes work for GA criteria that is no longer pertinent.


#### Graduation

* Promote `--experimental-allowed-unsafe-sysctls` kubelet flag to kubelet config api option

this flag does not exist.

it was changed to allowed-unsafe-sysctls and no further action is needed.

This was done, but it was done post-beta so I will keep it in GA criteria and add it into implementation history.

For some reason the issue was still open despite this having been fixed so I closed that issue.
