That's funny because one of the reasons I want to use UEFI firmware
is to get rid of grub (I don't like it and the way it has become
such a bloated beast): since /boot is vfat and has its own
partition, I prefer use a much simpler bootloader such as
gummyboot.

Ditching the bootloader is possible:

Well yeah it's possible but not currently usable IMHO. It means that you
need to build your own kernel, include in this kernel the initramfs
image and you need to redo the whole process if you want to change a
single option in the kernel command line.

It seems to me that you should be able to create a raid1 v1.0 MD array
of your EFI support partitions, and put the combined and signed
kernel/initramfs onto it (mirrored to all member drives).

Are both v0.9 and v1.0 MD  put their metadata at the end of a partition
? I thought only v0.9 would do that.

Then set the UEFI bios to try each device's ESP in turn.

Untested ... :-)

I'll do :)

Thanks
