I have determined that the root cause of the ZFS boot issue reported
here is in the content generated by update-grub.  The initial entry for
'Ubuntu (lowlatency)' is using $menuentry_id_option 'gnulinux-simple-
dev/sda4' which fails to load the zfs datasets at the initrd.  The menu
entry for 'Ubuntu Focal Fossa (development branch)' uses
$menuentry_id_option 'gnulinux-rpool/ROOT/ubuntu_xxxxx', also used by
the advanced options.  These entries boot normally without errors.

The update-grub command is part of the grub2-common package, and should
be updated to correct this issue.

** Package changed: zfs-linux (Ubuntu) => grub2 (Ubuntu)

** Changed in: grub2 (Ubuntu)
       Status: Fix Released => New
