 * `compression=[uncompressed,gzip,estargz,zstd]`: choose compression type for layers newly created and cached, gzip is default value. estargz should be used with `oci-mediatypes=true`.
 * `compression-level=[value]`: compression level for gzip, estargz (0-9) and zstd (0-22)
 * `force-compression=true`: forcefully apply `compression` option to all layers (including already existing layers).
-* `buildinfo=[all,imageconfig,metadata,none]`: choose [build dependency](docs/build-repro.md#build-dependencies) version to export (default `all`).
+* `buildinfo=true`: inline build info in [image config](docs/build-repro.md#image-config) (default `true`).
 * `buildinfo-attrs=true`: inline build info attributes in [image config](docs/build-repro.md#image-config) (default `false`).
