A while back when I was trying to do the whole encrypted ZFS root, the info
on Grub seemed to show that it didn't support loading ZFS as a booting
device. So it needed a separate boot partition (which I setup as a
soft-raided ext4). Later I moved to using gummiboot and uefi however that
apparently
Roger,
I got it from my grub.cfg config file. It looks like that's how you access
"root" zfs volume.
If I have
/
/volume1
/volume2
in grub I could access it
$disk/@/
$disk/volume1/
$disk/volume2/
Looks like just a convention but didn't dive into it.
btw, just to clarify my setup, currently
