Description

containerd v2.0 enabled the Transfer API by default.

This broke ctr images import --all-platforms:

$ ctr images export --all-platforms hello-world.tar docker.io/library/hello-world:latest
$ ctr images import --all-platforms hello-world.tar
ctr: rpc error: code = InvalidArgument desc = unable to initialize unpacker: no unpack platforms defined: invalid argument

Workaround: disable the Transfer API ( --local=true )

Steps to reproduce the issue

See above

Describe the results you received and expected

Received: ctr: rpc error: code = InvalidArgument desc = unable to initialize unpacker: no unpack platforms defined: invalid argument

Expected: the image should be imported, and it should be unpacked for the default platform
