Nice toy! Those things are getting rave reviews.

OK, I have to ask: why? Grub can multiboot just fine on UEFI without help.

As an example, I have a Thinkpad T420 booting Windows 10, Debian 11,
Fedora 35, Deepin 20 and Ubuntu DDE 21.10 using no additional tools at
all. It has also had Elementary OS 6.1 on it for a while.

(Pop!_OS screwed it up nicely because it and only it uses
systemd-boot, so I just formatted its partition and replaced it.)

OK, again: how?

I have the OEM kernel  on one machine; I used the method described here:
https://wiki.ubuntu.com/Kernel/OEMKernel

However, that for now seems to stop at 5.14 (`linux-oem-20.04d`) and I
can't find newer.
