### Exporting/Importing build cache (not image itself)

#### To/From registry

```
buildctl build ... --export-cache type=registry,ref=localhost:5000/myrepo:buildcache
buildctl build ... --import-cache type=registry,ref=localhost:5000/myrepo:buildcache
```

#### To/From local filesystem

```
buildctl build ... --export-cache type=local,store=path/to/input-dir
buildctl build ... --import-cache type=local,store=path/to/output-dir
```

The directory layout conforms to OCI Image Spec v1.0.

#### `--export-cache` options
* `mode=min` (default): only export layers for the resulting image
* `mode=max`: export all the layers of all intermediate steps
* `ref=docker.io/user/image:tag`: reference for `registry` cache exporter
* `store=path/to/output-dir`: directory for `local` cache exporter

why isn't tag (or name) a supported import/export option for local?
