I think that's fine, but @dfr has the final say.

Podman should also be updated in the quarterly branch too. If dfr@ allows it, remember to add MFH to the commit message.

I ran this through poudriere on 15.1 amd64 & aarch64.

Will commit to quarterly as well, just doing some final testing before pushing.
