There's no longer an 'efi' so that's good.

All OK.

Why two EFIs?

One of them's unnecessary but if you want to have both, you have to
have them both in the efibootmgr invocation.

All OK again.


Can you create an entry for your kernel in 40_custom and test it?

Take a look at grub.cfg. I doubt that grub-mkconfig looks for a kernel
in '/boot/machine_id/kernel_version/' or that it recognizes 'kernel'
and 'initrd' as valid names for a kernel and an initramfs.
