This isn't a hack; it's the same approach taken by other filesystems with subvolumes. Mention this explicitly. Explain that containers are exposed as disks on their own right. A conclusion was made based on this fact, but it was not explicitly called out. Signed-off-by: Hugo Osvaldo Barrera <[email protected]>

| `diskN` (`N` >= 1) could be a disk image or an external disk, but more likely is an *APFS container*. This is a hack that Apple came up with to represent subvolumes. The "partitions" within such a disk aren't real partitions, they just represent volumes within one APFS container. The container itself exists within a physical partition in `disk0`. That means that for APFS operations, for example, `disk0s2` and `disk1` could mean the same thing, the former referencing the container by its physical partition, and the latter by the virtual (*synthesized*) disk number. | ||
