forgot to add a reference to:
https://uapi-group.org/specifications/specs/boot_loader_specification/
(as it took me a short while to find where the entries syntax is defined)

thanks -- works as expected for my RAIDz1 2-disk setup!
Although not in the scope of this patch, I want to note that the entry
is not created for ZFS GRUB installations (be it on legacy non-EFI, or
secure-boot EFI), as opposed to LVM GRUB installations.

For if anyone wonders -- there's a 'z' that sneaked in here. I initially
tested against a ZFS RAID 1 two-disk mirror.
Just to make sure, I now also tested against a ZFS RAIDz-1 three-disk
installation. As expected, the patch works fine for that as well.

Thank you all for testing this so quickly - sent a new version (with
bug-reference and grub-handling):

Thanks for working on this! This is certainly something that quite a few
people have asked for over time.
For reference:
