When starting containerd with a config file version 2, I see several unknown fields error:

@AkihiroSuda asked me to report this, as even version 1 should be migrated.

Steps to reproduce the issue

  1. Copy the containerd config I posted here and name it test.toml
  2. Copy it to the root of the containerd repo
  3. On the containerd repo, run: make && sudo make install && sudo bin/containerd --config test.toml
  4. You will see the messages I pasted as containerd boots, no need to do anything else

Describe the results you received and expected

I expected the whole config was migrated fine. Although I'm not 100% sure this means it is not, it seems it isn't. If it is, then probably we should improve the error messages in some way

What version of containerd are you using?

2.0.0

Any other relevant information

Here is the full output when starting containerd with that config, in case it helps:
