Thanks. That makes it looks like the support for ZFS within grub can handle
raidz, so a good sign.

Ooh. That's a little odd, but also notes that it frequently goes out of date.
I may have to look for an alternate reference to find out what features grub
is known to be confused by, and make sure none of those are turned on. If
someone has a good pointer to info on these in grub, of the grub version
we were recently discussing for use on sparc64 debian, I'd appreciate it.

Booting an installer may not work, though, since I need ZFS support in the
system I'm running. To get a d-i with ZFS built in, I presume I'd have to
build my own. Which I could, but don't know that I know how. If I can use
something like debian-installer, I'd like to, but need one that can mount
up my ZFS filesystems. Otherwise, I guess I need to find a guide of how to
do it the lower-level way. ( looks valuable)
