GRUB_FORCE_PARTUUID set, attempting initrdless boot.
Linux version 5.8.0-1008-kvm (buildd@lcy01-amd64-016) (gcc (Ubuntu
10.2.0-13ubuntu1) 10.2.0, GNU ld (GNU)
Command line: BOOT_IMAGE=/boot/vmlinuz-5.8.0-1008-kvm
root=PARTUUID=f6bea054-a6e1-4734-91e2-eb6425be905b1
x86/fpu: x87 FPU will use FXSAVE
BIOS-provided physical RAM map:

So it is not obvious if grub output will be visible in the console log,
because GRUB_TERMINAL=console might not be set.
Also, previously the first message from the boot was from kernel. But my
patch introduced 'GRUB_FORCE_PARTUUID' option.
Also, somehow on the minimal cloud image 'Ubuntu 20.10' was detected on
/dev/sda1 - aka the only Ubuntu that there is..... and somehow I'm
getting 10s grub menu prompt.
It almost feels like maybe kernel should be emitting dmesg message that
it performing initrdless boot. rather that just:
EXT4-fs (sda1): mounted filesystem with ordered data mode. Opts: (null)
VFS: Mounted root (ext4 filesystem) readonly on device 8:1.
Run /sbin/init as init process
