Trouble running podman + kind

[caniko]

/kind bug

Description
I am tyring to run kind with podman, but getting errors. Please see the issue I made on the kind side.

Steps to reproduce the issue:

The following fail:
Running sudo kind create cluster
Running sudo KIND_EXPERIMENTAL_CONTAINERD_SNAPSHOTTER=fuse-overlayfs kind create cluster
Running sudo KIND_EXPERIMENTAL_CONTAINERD_SNAPSHOTTER=native kind create cluster

Describe the results you received:
Output every time:

The segfaults seem to be coming from kind code, not Podman, so I don't think we can help here. I recommend opening this against the kind Github. Going to close given that, but if they end up sending you back here with more details about a Podman problem, we can reopen.
