Public bug reported:
Focal Fossa Beta ISO installation with Root on ZFS as the only thing
that is special about this installation.
Installation seemed to proceed without error, but upon reboot the system
booted to a blank grub prompt. There were no kernel options to choose.
Looks like my UEFI machine choose to boot ubuntu (sabrent) by default.
If I interrupt the boot process and choose the non-intuitive sabrent
option then the machine will boot.
Since there is no mention in the release notes of having to fix an issue
such as this, post installation, I'm assuming that this is unintended
behavior.
Gigabyte B450 I AORUS PRO WIFI-CF Motherboard with an AMD Ryzen 3 3200G
processor and a Sabrent m.2 storage device.
