A brief line about why "zpool" and "tank" could be useful as they are used throughout the documentation without any explitaion of why or how those labels were used. I think zpool was used because it was a zfs-pool to get away from the "tank" name which I always thought was an odd name but it persists in documentation so I would expect it to be mentioned.

I don't find "== Dataset Administration" clear. Perhaps "== Filesystem Dataset Administration"?

If "zfs Administration" is changing to "Dataset Administration", I think the title for chapter 22.3 also should be changed from "zpool Administration" to "Pool Administration" for consistency. In this way, titles can imply what they do rather than just the name of command, because most users who read this handbook are new to zfs and thus have zero knowledge about zfs and zpool command.
