Remove reference to EFI(?), explain that the new space
is beyond the GPT for whole-disk vdevs, and add section noting how it
behaves with partition vdevs in terms of how the user is most likely to
encounter it ‒ the previous phrasing was confusing
and seemed to indicate that "zpool online -e" will be able to claim
GPT[whatever, ZFS, free space, whatever]
into
GPT[whatever, ZFS, whatever]
but that's not the case, as it'll only be able to do so after manually
resizing the ZFS partition to include the free space beforehand, i.e.:
GPT[whatever, ZFS, free space, whatever]
GPT[whatever, [ZFS + free space], potentially left-overs, whatever]
# zpool online -e
GPT[whatever, ZFS, whatever]
