@radar07 sure

@Luap99 I wonder if we have to write a brief description about pasta as the default rootless network in place of slirp4netns in the man page. Do you have any suggestions?

Yes that would be good, pasta works a bit differently so adding it there would be good. Maybe the pasta section here could serve as a string point: https://blog.podman.io/2024/03/podman-5-0-breaking-changes-in-detail/

The default is also wrong in https://github.com/containers/podman/blob/main/docs/source/markdown/options/network.md

@Luap99, Thanks for letting me know. I created a PR with few changes that might get this done. Also, please let me know if you have any other suggestions.
