> if you try to delete the root directory on s3a, you get politely but firmly
> told you can't
> {code}
> 2016-03-30 12:01:44,924 INFO s3a.S3AFileSystem
> (S3AFileSystem.java:delete(638)) - s3a cannot delete the root directory
> {code}
> The semantics of {{rm -rf "/"}} are defined, they are "delete everything
> underneath, while preserving the root dir itself".
> # s3a needs to support this.
> # this skipped through the FS contract tests in
> {{AbstractContractRootDirectoryTest}}; the option of whether deleting / works
> or not should be made configurable.
