Re updating boot blocks: It's not a requirement. It's a diagnostic question
to see what code we're dealing with.
The only time it's been required was the ZFS update to OpenZFS after a
zpool upgrade because the latter
introduced new features the old boot blocks would reject as being a valid
ZFS that it recognized.
