Note that this is a slight behavior change, because now the first partition's usage which is not simply 'partition' will become the disk's usage. Previously, if any partition was 'mounted', it would become the disk's usage, then 'LVM', 'ZFS', etc. A partitions usage defaults to 'partition' if nothing more specific can be found, and is never treated as unused for now.
