### ACL, Policies

Amazon has 2 access control mechanisms in S3: ACL (legacy) and policies (new one).
Garage implements none of them, and has its own system instead.
See Garage CLI reference manual to learn how to use Garage's permission system.

- **GetBucketVersioning:** Stub implementation (Garage does not yet support versionning so this always returns
"versionning not enabled").

- **ListObjects:** Implemented, but there isn't a very good specification of what `encoding-type=url` covers so there might be some encoding bugs. In our implementation the url-encoded fields are in the same in ListObjects as they are in ListObjectsV2.

- **PutBucketWebsite:** Implemented, but only stores the index document suffix and the error document path. Redirects are not supported.
