Research direction
The issue asks to adopt Go 1.13 error wrapping (errors.Is/errors.As) throughout the gvisor codebase. Review the blog post linked for guidance. Look at existing error handling patterns in files like pkg/sentry/... and pkg/... . Comments in the issue may provide direction on priority areas to refactor.
