Processes should print files and folders and exit

Steps to reproduce

runsc debug logs (if available)

The documentation doesn't specify how to capture debug logs in containerd. Could you please provide guidance on how to do this? I'm happy to provide any additional information if needed. Thanks!

Can't say much without runsc debug logs. To specify runsc flags, see https://gvisor.dev/docs/user_guide/containerd/configuration/. The last section "Example: Enable shim and gVisor debug logging" should have instructions.

Got working with crictl. Thanks.
