As far as I know, this is lore than surfaces periodically in the lists. =
It was true in Solaris (at least in the past).
But unless I'm terribly wrong, this doesn't happen in FreeBSD. ZFS sees =
"disks", and they can be a whole
raw device or a partition/slice, even a gnop device. No difference.

That's why I mentioned in freebsd-fs that we badly need an official =
doctrine, carefully curated, and written in holy letters ;)
