Though, the conversation earlier covered that grub supports ZFS. You say above
that booting from a ZFS partition using blocklists doesn't work. There's
something I'm not understanding in the space across those two statements.
FreeBSD has a zfsbootloader, which is what I've been using. And, whether
I can use ZFS or not, I don't think I want to start down the path of booting
from magnetic media that isn't replicated onto another spindle. If debian
will let me boot from ZFS, how do I do it? If it won't, are there other options
to boot from mirrored filesystems?

I believe the same, I don't know what that error message means. I know that
I do have sun labels, not GPT labels, on my disks.
